Finding two coterminal angles given in radians
Вставка
- Опубліковано 8 лют 2025
- 👉 Learn the basics of co-terminal angles. An angle is a figure formed by two rays that have a common endpoint. The two rays are called the sides of the angle while the common endpoint is called the vertex of the angle. We measure angles starting from the positive x-axis, i.e. the initial side of an angle measure is usually the positive x-axis. The angle measured in the anti-clockwise direction is called a positive angle while a negative angle is measured in the clockwise direction.
Two or more angles are said to be co-terminal when they have the same initial and terminal sides. Coterminal angles are found by adding/subtracting 360 degrees (for degree angle measure) or 2pi (for radian angle measure) to/from the given angle.

Let’s just remember, this man has better videos for his lessons than any of our math teachers on zoom
Ad: “aRe tHeSE tEN yEAr OlD mAtH viDEoS rEAlLy hElPinG?”
Me: “Yes”
It’s ironic because I’ve been seeing that video for years and they have yet to change their advertisement
I got the same ad while reading this. Math doesn’t change so I don’t know why that was their appeal
yeah matt look up here
+Valentina Cracchiolo fucking matt
BEST TEACHER EVER!
schools need teachers like you, tbh.
thank you very much just doing my part
Geez louise Matt! Not paying attention during pre-calc class, what a goon.
seriously
Free Math Videos I am so serious, you have to put down the law on to Matt. Free Math Videos my one piece of advice is that you have to strike fear into your students just like the great man Martin Luther during the Protestant Reformation.
thanks for the input
Free Math Videos Stay real
That is awesome! I know you spent a lot of time either watching videos or preparing for the test, so congrats to you. I am very happy to be a part of your success.
You are truly a legend
awesome! so happy to be able to have helped you out!
bro you're a legend
easily one of the best instructors i’ve found on youtube 👍 thanks for the help
Thank you very much for the clear explanation. It means a lot to me. You truly have a gift for teaching math. It may not seem like much, but your ability to easily convey thoughts is outstanding. Keep it up. I'm definitely subscribing.
Soooooo helpful! My teacher is not so good at explaining things and this cleared everything up! THANKS!!
You explained this 1000x better than my professor. Thank you so much.
You are really pulling me through math right now man.
Omg I literally learned more in this video than in my entire 70 minute class, dude you are literally saving my grade
You're the only reason I am understanding college Trigonometry - THANK YOU!!!!
Thank you so much I was absent in school when we learned this and when you taught it it made sense and now I understand it thankfully before my quiz tomorrow
9 years later and you’re still my savior
Forever greatful for these videos! Currently reteaching myself pre-calc trig (which I haven't done since 11th grade) in order to take a math placement test for college. These are really saving me!
Thank you for posting these videos man. It’s been a great help
your very welcome, you better get a good grade on your math test. Keep up the hard work let me know how you do.
Thank you so much sir! I always watch your videos and it helped me a lot. I never thought in my entire life that I could understand Math. Thank you so much!
My professor wants to sit down and write bs on a projector. Not really teaching us anything lately so thank you for not taking shortcuts in your teaching!
this guy actually teaches!! thank you! my teacher never explains anything and we all literally have to learn the lessons ourselves. This was great
+Karina Chavez yep sure do, still teaching, sorry you are having trouble but glad my videos have been able to help you
these videos saved me throughout high school man thank you
and college lmaoo
You're a hero to students all over the world
i was so lost until i watched your videos. thank you!
thank you! This is going to get me a good grade on my math test! Keep doing what you're doing. Thanks again!
I saw Matt the other day... he took my order at burgerville..
your welcome!
Thanks for explaining this more clearly than my trig professor!
amazing shortcut, much easier than having to draw everything out!! thanks again!!
+Pamela Acosta agreed!
you explain this really well, i appreciate the help very much.
awesome, so happy to help. I hope a lot of my videos will be of assistance to you. What happened?
THIS MAKES SO MUCH SENSE NOW, THANK YOU 😭
you are very welcome!
Thank you, my professor went through this in such a haste, now I can supplement my notes.
that's why I can created this videos, glad to be able to help you
Thank you so much for making these videos, my math professor skips through these little things and expects us to figure it out on our own. When I try to add 2pi to -7pi/2 I get -3pi/2 as my coterminal angle, but in my solutions manual it says pi/2 is the coterminal angle. Am I doing something wrong with that problem?
coterminal angles can be positive or negative, if you add 2pi again that is also a coterminal angle which is pi/2 FYI there are infinite coterminal angles as you can add or subtract 2pi infinitely
will do more and more videos to come
dear flipping god thank you
Anthony Sgroi you are very welcome! happy to be able to help you out!
My man still killing it in the classroom. Even after last night's bar fight
Rugby game
THANK YOU SO MUCH
this is a time capsule for the future. hello from 2021
where did u get the 2 pie from
guess what i got on my math test? 93 % !!!!!! I benefit so much from watching your videos!
thank you for this 🙏🏼
thanks a good video that refreshed my mind
absolutely! happy to help!
Thank you so much for making this understandable!
Ari Astorga you are very welcome!
It's been nearly 10 years since this was posted, is anyone else curious what Matt is up to these days?
CBT
Yo your such a G. Bless you
Thanks man
legend has it matt still isn't looking up there
Haha
Haha
Thank you
Goddamn it, Matt, pay attention.
Video was hugely helpful! Also were you recently in a fight for this video?
thank you, I play rugby which i guess is like a big fight
Really help ful
+Refath Bari happy to help
Thank you so much!
My man Matt got caught lacking
Thank you.
you are very welcome! happy to help
thank you!!!
thanks helped alot
+Daniel Racko you are very welcome!
theres always that one kid he bout to throw hands with in class
CMON MATT IM TRYING TO LEARNNNN
Goat
for the middle one why is it +2pi it doesnt seem to go 360°
+emanuel talavera 2pi is the same as 360degrees
When he said fractions I also said "no"
this is not always true to add or subtract by 2pie depending on how high the fraction is you have to then add or subtract by 4pie so maybe set better examples.
I don't really understand the shortcut/counting step, it just further confused me
Why 8/4?
because that is the same as 2 but has a denominator of 4 so I can subtract fractions. Because to subtract fractions the denominators must be the same
Oh. Ooooh. Ooooooooh! Thank you. I get it. >o>
my god it hurts me to see a math teacher that actually tries to help students the beauty of math and ends up getting such little ungrateful/sarcastic little shits just slowly building rage in a motivated teacher. i hope you keep doing videos so the real students(regardless of age/level) that actually appreciate you will find your videos and help you maintain your sanity as you go about your days teaching babies that reject the nutrition of math as you try to spoon feed formulas(pun intended) and basically babysit them. also, DAMMIT MATT ITS THE BASICS
+Aziz RehmanVevo that is exactly why I make videos, helping out all students looking to learn
Matt got bodied lol
Speaking of pie, I'm going to go eat some... cheesecake.
So I guess I won’t completely fail my exam 👍🏼
god damn it matt pay attention
Haha
2019 anyone?
We have all sinned and fallen short of of Gods glory sin is terrible because of sin we are separated from God but gladly here is the good news Jesus Christ came and walked this earth for everyone taught us the perfect way to live and how we should live and he died for our sins because we need a sacrifice to pay the price for our sins since our sins deserve hell if we live in sin but also more good news Jesus rose from the dead three days later we have to leave the sin behind and put it away and live new with Jesus this world is like a vapor it passes away but your eternity is forever and it is up to you what you want to do with it…
MATT!!!!
what did he do this time?
