I watch another channel called Illinois energy prof, and he does the same thing. But because of his shirt pocket, its pretty obvious that its mirrored.
I’ve been severely struggling with the trig portion of calculus for a while. I narrowly survived trig because my professor didn’t really make sense to me. I’m not kidding when I say this saved my whole academic career. THANK YOU!!!!
My favorite parts are when she finishes a new section and when she’s done looks at the camera like “I know, I know.” 😂😂 but really this helps A LOT and helps me look at it more clearly. I have a learning disability and when something is very busy I get overwhelmed so to be able to chop it up like this and make sense of it means everything to me.
Couple things that I observed which helped me remember this: (Cos, Sin) - remember CS for computer science. Also, 1 == Sqrt(1), which makes the pattern even more obvious. Also 2 == Sqrt(4), so the pattern is actually quite nice if you look at it this way. Thanks so much Nancy, awesome vid.
This is an easier way : You only need to memorize the degrees . You can find the radian by multiplying the degree times pie over 180. And you can find the x and y values by inserting the same degree with cos being x and y being sin .Note on the calculator : switch degrees to radians when finding the radian of the degree.
Man you the goat! All you have to know is the degrees which there’s an easy pattern to and you can figure out the rest. You the BEST! Thanks man!!!!!!!!!!!!!!!!!!!!!!
You need to be able to think in radians in higher math. If you need to change to degrees, you are handicapping yourself for the future. Easy now, hard later.
Hi Nancy, hope you are well. I wrote on another video of yours a few weeks ago. I am currently doing engineering as a mature student and have not done maths in a long time and finding your videos very helpful. Thanks for being patient and setting a calm teaching mood where the information flows very easily. This technique or style of yours is the right way to teach. There is often so much angst in learning and the teacher adds to the chaos of it by their personality I think. The end result, is confusion and lack of transfer or knowledge as I am finding from my online uni lectures which are often presented by 'junior' Phds who have no idea of how to teach. It is almost like, hey this is what we know and we are so great - aren't we? Can you be so great as us? This is the kind of the message I get. Hardly any effective transfer of knowledge. Text books are written like that too, just a representation of the writer's ego, particularly how formulas are written with flamboyant text - which just adds to the fear of what is possibly a simple formula. So a big thank you for who you are and how you do this. Please keep up the good work and I think there will always be a need for these videos and this teaching style. You remove the fear of maths which is, I think the biggest hinderance to many people learning the subject. I have seen in my life that often something learned in fear is forgotten easily as your mind tries to heal up the trauma of it - the opposite in some circumstances is also true where you cant forget a bad experience but I think generally, if something is taught in a relaxed, everyday kind of way, it stays in your mind longer (it does for me anyway). The maths teacher has always been the feared one for me (and for others I have felt, from watching and talking to other students in the past who have been in class with me particularly when I was in high school many years ago. Most people have a mini panic attack before their maths exam - not so in other subjects I thought. I think this stems from historical teaching techniques over generations). I feel there are so many great minds out there which have not been taught properly and the end result are mediocre careers and lives. So, God bless you and thank you for what you are doing for humanity (you probably haven't though of it in that way but you are helping many I think with your teaching). Have a great day!!!
Calculus is so hard. I'm really struggling with it. These videos are actually helping. Your explanations plus my instructors worksheets and studying is really helping. Thanks for putting in some good work here.
And nothing beats a smart woman, nothing! You are a complete joy to watch amazing! Glad I came across this, not sure how but it’s extremely wonderful to watch and learn.
Cripes! You made that SO straightforward, interesting, very easy to understand and how to remember. And your whole style is so serene. Thank you so, so much.

No I think he was saying that real Christianity actually supports such things. What people don't think about is the fact that Christianity didn't start until the book of Matthew was written. If you don't believe it, then that's just fine with me, but I love my belief system. According to scripture, Jesus was a supporter of women and still is a supporter and for equal rights. He stopped barbaric people from stoning a woman to death because she cheated on her husband. My stupid satanic x wife cheated on me too, but realized I was better, but I didn't want to be married so I let her go. ugh! It's a long story that I'm not getting into. Ironically, because I didn't want to kill her, she wanted to kill me if that even makes sense! LOL. If you think satanists are rebels and for woman, then you're very deceived. The problem isn't with Christianity. Rather, it is with religion. Oh by the way, when I was in college, I controlled the curve, and that was at a world renown university that is even more recognized than MIT! I was a middle school drop out, but in my 20's I went to a world renown university and was better at higher mathematics than people who prepared for it from the time they were around four years old. I beat the oriental students. I posted my grades on my google page. The only one who was almost as good as I am is a little Jewish Woman. I don't like telling people my life's story, but I was once married to an crazy female who happens to be a millionaire, and she got it in for me because I didn't care about her cheating on me, and I didn't fight for her to come back to me? Gender doesn't determine a person's level of intelligence, or does it determine his/her level of sanity, or should I say lack thereof. My x-wife actually has a high I.Q., but she's not sane. I know the common brain washing tactic of today is to become enemies with males, but it's pointless and stupid. I'm not out to get you. I'm not a misogynist, nor am I a satanist!
I do empathize with the female gender. For example, the old dogmatic fanatics didn't allow women to vote until what? 1920? That's called women suffrage. The witch hunts weren't done by Christians either. It was satanists incognito who practiced the precepts of the Codex Gigas which dates back to the 12th and 13th century around the same time that the witch hunts occurred. As for me, growing up. I was a liberal minded hippie. That means that I never wanted to enslave females, and I always wanted females to be treated as equals and with respect. Ironically, I was trapped into marrying a girl because, after 3 years of dating, she wanted to trap me because she thought I was cheating on her and that if she married me, then I wouldn't cheat and she could control me. I'd forget about the whole thing if she would have too. I mean, damn! We were teenagers when that happened. Oh, here I am telling you my life's story. Okay, I might as well finish. I married her because her mother took her to planned parenthood and threatened to force her to get an abortion if I did not! Had we not married, I would've still lived with her, and/or paid support. She didn't want support. She wanted me the crazy girl. Well, that was understandable since we were BOTH stupid teenagers, but people do need to grow up some time. By the way Laur T. How old are you? LOL

I had trouble remembering xπ/3, xπ/4, xπ/6 so I ended up grouping the front numbers to (1,2,4,5)*π/3 (1,3,5,7)*π (1,5,7,11)*π and this works pretty well. Thanks Nancy!
i had developed this same presentation of the unit circle...as a math lab instructor....about 1977 at a jr college in Washington State....and she is right is very important to see and under stand the system relationships ...
Thank you so much for this! I FINALLY have a decent understanding of the unit circle thanks to your explanation of the patterns and which of the coordinates is largest/smallest!
Mindblown. I did not notice these patterns in the unit circle when taking Trig. I couldn't memorize the unit circle. I don't think I need to, but I can remember the patterns and produce an unit circle. THANK YOU SO MUCH!
Always enjoy your math videos, Nancy! Excellent video on the unit circle. I remember drilling this into my brain and am glad I did because it comes in handy in so many math classes. I never found an easy way to memorize it other than just studying the circle over and over again.
Be my teacher, please! My teacher is useless, I need somebody like you! At school, they just gave us a sheet and told to memorize without explaining WHY the numbers are the way they are!
I really needed to learn this. Helps to be able to cut the pizzas i make at the pizzeria. So, room mates won't fight over who gets the bigger slices of pizza. Thanks.
Thank you for all the people actually offering helpful tips and suggestions in the comment, and not the same "OH SHE HOT" & "MATH WITCH WRITES BACKWARDS" comments as everyone else. Thank you Nancy please keep up the good work.
I tend to explain this using the series sqrt(0)/2 - sqrt(1)/2 - sqrt(2)/2 - sqrt(3)/2 - sqrt(4)/2. I have the impression it's easier to remember than 0-1-sqrt(2)-sqrt(3)-2. For the rest, keep up the good work!
Hey Jason, if you still need help understanding subtracting mixed numbers or ever need any more help in math, I recommend you download the Kadama app on the app store. It has many excellent math tutors that can help you out at the budget of your choosing!
Thanks! You are awesome! This definitely will help to reduce my reliance on a calculator while simplifying answers, specifically involving inverse trig.
I never saw that before, thank you so much, we only did it by 90 degrees in my class but this is much better and we never whet over the cos and sin values in the points of the circle. So big thanks to you!
Thank you so much for these videos! I had to remove myself from a Pre-Cal class with an A+ because my teacher is so lazy and doesn't seem to want to be there. I am testing out and you are a big help. Thank you so much!!
There is an easy way to remember this using your hand. She doesn't explain it in the video but it came back to me afterwards. I suggest looking up how to memorize unit circle using your hand.
Fantastic video! Explaining a complex subject in a simple way (for people like me) is the sign of true genius! Super clear way to teach thousands of years of knowledge very quickly. Also I am trying to understand your disposition! It is almost like you are suppressing some intense laughter. What is happening by that camera??? Thank you for the video NancyPi!
This is fantastic. Thank you. Once I get the pattern down as you described, it's super easy. I only need to memorize the 1/2, sqrt(2)/2, and sqrt(3)/2 and the rest falls into place.

@@jonathanrenteria5781 "So as you can see, this is rapidly turning into a disaster" that on the front with a picture of this pi graph on the back. or visa versa. I would buy.
If you drew PI/3 before PI/6 you could simply count the quadrants to find the right expressions, like this: Getting the four points the axis touch: If we know that the full circle is 2PI, and we divide the circle into four equally large parts, we can calculate that each part is 2PI/4 or just PI/2. With this information the four points should be: 1 * PI/2 2 * PI/2 = PI 3 * PI/2 = 3PI/2 4 * PI/2 = 2PI Then we can calculate our PI/4s. Since PI/4 is half of PI/2 we know that we twice as many parts i.e. 8 parts. And using the same technique as before we can calculate the PI/4s as following(note that since we halved our quadrant size, some quadrants of the PI/4s line up with the quadrants of the original points) : 1 * PI/4 2 * PI/4 = PI/2 3 * PI/4 = 3PI/4 4 * PI/4 = PI 5 * PI/4 = 5PI/4 6 * PI/4 = 3PI/2 7 * PI/4 = 7PI/4 8 * PI/4 = 2PI Now to calculate our PI/3s: This gets a little tricky since we really can't divide 2s and 4s to a 3. But using the fact that the number of parts is exactly double of the denominator of our radical (3) we know that there are 6 parts: 1 * PI/3 2 * PI/3 = 2PI/3 3 * PI/3 = PI 4 * PI/3 = 4PI/3 5 * PI/3 = 5PI/3 6 * PI/3 = 2PI And finally, we calculate our PI/6s: This can simply be done by the same method as when we calculated our PI/4s from our PI/2s, i.e. doubling the number of parts: 1 * PI/6 2 * PI/6 = PI/3 3 * PI/6 = PI/2 4 * PI/6 = 2PI/3 5 * PI/6 = 5PI/6 6 * PI/6 = PI 7 * PI/6 = 7PI/6 8 * PI/6 = 4PI/3 9 * PI/6 = 3PI/2 10 * PI/6 = 5PI/3 11 * PI/6 = 11PI/6 12 * PI/6 = 2PI
We need to learn more trig. You make things sound the easiest of anyone I've ever heard. Let's learn more or this is "...rapidly turning into a disaster."

Thank you so much for these videos! I had to remove myself from a Pre-Cal class with an A+ because my teacher is so lazy and doesn't seem to want to be there. I am testing out and you are a big help. Thank you so much!!
I especially appreciate that you are writing everything backwards. And thankyou for the excellent explaination.
saving my math grade, yet again! thank you
Thank you my queen 👑 you've made my life much easier
There is an easy way to remember this using your hand. She doesn't explain it in the video but it came back to me afterwards. I suggest looking up how to memorize unit circle using your hand.
You explained it prefect! Watch many videos but your method I understood better than others... Thanks!
Hey, big fan of ur channel, thanks for all the videos they are truly a big help. Keep up the good work!
This is the first time ive been able to learn the unit circle in over two years
"Unit circles are {lots} of fun.." haha that is my kind of enthusiasm.
Nancy, you are fantastic teacher
Fantastic video! Explaining a complex subject in a simple way (for people like me) is the sign of true genius! Super clear way to teach thousands of years of knowledge very quickly. Also I am trying to understand your disposition! It is almost like you are suppressing some intense laughter. What is happening by that camera??? Thank you for the video NancyPi!
This is brilliant Nancy!!! Thank you for making math videos!
been struggling in school, thanks!
This is fantastic. Thank you. Once I get the pattern down as you described, it's super easy. I only need to memorize the 1/2, sqrt(2)/2, and sqrt(3)/2 and the rest falls into place.
I have a test tomorrow on this and this was exactly what I was looking for. Thank you!
You are very smooth and lively
Hi Nancy! Your explanation is the best I have ever seen!!
Hey Francois, if you still need help understanding subtracting mixed numbers or ever need any more help in math, I recommend you download the Kadama app on the app store.
It has many excellent math tutors that can help you out at the budget of your choosing!
Mark Sanchez Hi Mark, thank you for the feedback, I will give the app a go!!
its been 2 days in my precal 2 class and this made so much sense
Hi Nancy. I find it helps my students to know that the numbers are root(0)/2, root(1)/2, root(2)/2, root(3)/2, and root(4)/2, simplified.
2nd year as EE major and I still come back here :)
I understood this perfectly in 7 minutes, thanks for teaching me what my teacher couldn’t teach ):
Has anyone asked how long it took her to practice the perfect mirror handwriting on the glass board? I am stunned! And of course, the whole thing is well explained- and nice to watch!
I literally passed my exams by watching you way back in college.
I’d learn math so much better if I had a teacher like Nancy 😍😍
Holy, I always had problems remembering this. This makes everything a hell of a lot easier. Thanks!
wheres Nancy merch
dude, I will totally buy
Honestly, I would buy it. If she had a hoodie saying something like "Your teacher sucks, but I don't". I would rock it with pride
@@jonathanrenteria5781 "So as you can see, this is rapidly turning into a disaster" that on the front with a picture of this pi graph on the back. or visa versa. I would buy.

I love 3,1415926, NCP, thanks, so clear. Class full of pi's!
You are just plain awesome, love your way to explain things!!🥰🥰🥰
Thank you very much for all of your content! It is much appreciated!
I don't know what shes better at. Math or stealing my heart
If you drew PI/3 before PI/6 you could simply count the quadrants to find the right expressions, like this:
Getting the four points the axis touch:
If we know that the full circle is 2PI, and we divide the circle into four equally large parts, we can calculate that each part is 2PI/4 or just PI/2.
With this information the four points should be:
1 * PI/2
2 * PI/2 = PI
3 * PI/2 = 3PI/2
4 * PI/2 = 2PI
Then we can calculate our PI/4s.
Since PI/4 is half of PI/2 we know that we twice as many parts i.e. 8 parts. And using the same technique as before we can calculate the PI/4s as following(note that since we halved our quadrant size, some quadrants of the PI/4s line up with the quadrants of the original points) :
1 * PI/4
2 * PI/4 = PI/2
3 * PI/4 = 3PI/4
4 * PI/4 = PI
5 * PI/4 = 5PI/4
6 * PI/4 = 3PI/2
7 * PI/4 = 7PI/4
8 * PI/4 = 2PI
Now to calculate our PI/3s:
This gets a little tricky since we really can't divide 2s and 4s to a 3. But using the fact that the number of parts is exactly double of the denominator of our radical (3) we know that there are 6 parts:
1 * PI/3
2 * PI/3 = 2PI/3
3 * PI/3 = PI
4 * PI/3 = 4PI/3
5 * PI/3 = 5PI/3
6 * PI/3 = 2PI
And finally, we calculate our PI/6s:
This can simply be done by the same method as when we calculated our PI/4s from our PI/2s, i.e. doubling the number of parts:
1 * PI/6
2 * PI/6 = PI/3
3 * PI/6 = PI/2
4 * PI/6 = 2PI/3
5 * PI/6 = 5PI/6
6 * PI/6 = PI
7 * PI/6 = 7PI/6
8 * PI/6 = 4PI/3
9 * PI/6 = 3PI/2
10 * PI/6 = 5PI/3
11 * PI/6 = 11PI/6
12 * PI/6 = 2PI
We need to learn more trig. You make things sound the easiest of anyone I've ever heard. Let's learn more or this is "...rapidly turning into a disaster."
The most understandable method for me. Thank you nancy! I hope i pass my senior year of hs
Very good explanation. Thankyou Nancy.
There is no words to express how much beautiful and smart you are.Thanks a lot my dearteacher from Ethiopia(Eastern Africa).
this is pure magic! breathtaking beauty... beautiful! kabbalah!
