After struggling with this for a week, I said to myself, "Maybe the organic chem guy has a video. He has videos on like everything." Lo and behold, it's the first search result. I'm always amazed by the depth of knowledge and skill on this channel. Infinite thanks from a college student just trying to pass their precalc class!
Eversince online classes started, I'd always go to this channel to learn more about our Pre-Calculus subject and I've been getting pretty high grades. Thank you!
i think it's your voice that calms me down and how you explain out every little thing instead of talking fast and merging steps together. You are the best teacher out there

@@maevizzz it went really bad. The class average was a 58, I got a 52. Came outta the class with a C. It wasn't hard per se so much as the fact there were 50 percent more questions but the same 110 minute time limit. The whole class was still there taking the test after ten minutes over time. Instructor has to kick us all out.
Thank you, your videos have been a lifesaver for math this year. Unfortunately the instruction I'm receiving at school this year contains limited examples and my teacher isn't exactly the best at explaining and often tends to jump around on notes which means I get lost easily, plus we're learning a whole year's content in like 9 weeks and it's a cram. Again, thank you so much for making those videos, I love how you give lots of examples and explain in a step by step manner which I really miss from last year's teacher.
Nothing the comments don't say already... Your videos have once again been my secret weapon when it comes to mastering a topic I had no clue about just minutes ago. Watching this a couple hours before a Trig exam and now feel confident enough to take it.
i am panicking a day before my test that I couldn't solve simple questions like these. But now, I can solve some tough questions from my textbook. Thank you so much! You are a life saver!
Cramming for our quiz and I actually didn't learn anything from my teacher. My head aches looking at those things on the board and I thought I couldn't understand anything and thay I wouldnt understand a thing. Although I'm a bit late with the lesson, i would still want to thank you cuz you're saving my life.
The amount of pain and confusion with this topic is off the charts, I had this test and while I was doing the test I was damn confident about my answers but then the results came and I had like 3 items done correctly, This video really helped me
In class this was so frustrating I almost cried. But for the first two examples I paused the video and did exactly what you did. I feel a lot better now.
THANK GOD FOR THIS VIDEO!!! I was struggling with this concept for DAYS and a 24 minute video answered absolutely every question I had. Curse you, K12!
THIS VIDEO WAS A LIFE SAVER!!! helped me gain confidence knowing I could make mistakes and have the questions and errors I made be explained!!! ever since I started watching and doing the practice problems in the video my math test grades have gone from 70s and 40s to 95s and 100s!!!!!
Just know everyone you should always look at the hardest side and not just the left or the right. it's very easy to get stuck if you go with left or right not the side that is hard. Anyways just pointing that out. :)
Hey just here to say thank you for all the contents that you do. I passed my calculus course last semester, and it’s all thanks to your explanation. Wish you the best this year!
i cannot explain how joyous I am! i was unable to understand this for a year. my teachers and friends taught me many time but this man made it possible for me. And its my exam day when i watched this video. Thanks man
THANK YOU!! My Precalc grade hasn’t been the best and I need to understand this to bring it up, and your practice has been SOO helpful! Thank you!! (Im gonna get that A- at the end of this marking period if it kills me lol)
Would be appreciated if you did one about simplifying trig expressions. Been kinda confusing and difficult finding a way to rewrite problems while having no idea if I'm doing it right
I have a really good teacher but I was out for exams and missed this stuff and got lost but this video got me up to pase for free thx so much I'm willing to pay next time I'm struggling
This Video is a lifesaver!! Thank you so much!! I've been struggling for a couple weeks now and your video explained everything I needed to know in easy to understand steps.
For the last problem at 23:54 you can solve it quicker if you just convert tan(x) to sin(x) / cos(x) and then the top becomes sin^2(x) and you are done.
13:06 In question 5 it'd be easier if you take the more complex side of the equation and simplify it, I'm speaking this with prior experience and if you do that here is what you get: Sin(x) Tan(x) = (1-cos²(x)) / cos(x) => Sin(x) Tan(x) = sin²(x)/cos(x) - since 1-cos²(x) = sin²(x) => Sin(x) Tan(x) = sin(x) × sin(x)/cos(x) - simplifying the square on sin(x) => Sin(x) Tan(x) = sin(x) × tan(x) - since sin(x)/cos(x) = tan(x) Q.E.D
This video was very good. Thank you for your help. By the way, I used to have a teacher who taught this lesson using analogies that don't make sense. She refers to factoring as "chopsticks and a bowl" and refers to multiplying by the conjugate as "chunky one". Weird right?
Thank you sir 😭u're my savior. I have an exam is some minutes and I had no ideas how to solve this. N u just saved me. Thank you very much. God bless u sir 😭🙏
I searched tons of videos for the pre requisite for this which is 7.1 (fundament identities) this is 7.2 what helped me was just practicing questions over and over, to me 7.1 is harder to grasp then 7.2. So to anybody reading this go practice 7.1 questions once you get to this it’ll be a lot more easier to understand
I am so happy that I encountered this video. I have a test upcoming, and I had no idea what I was listening to in class. The problem was I understand it, but then I had trouble solving it. I did so much research on just Trig Id. This video made sense to everything! Thank you so much for making a video on it. I just wish it would show how to turn trig id into numbers. Does anyone know how to do so?
I love math, but when I lesson this It seems I want to give up, This lesson need extreme understanding in trigonometric identities and formulas. But when I prove it, I breathe conveniently.
Watching this for my first Mathematics module at uni, Without passing this we are not able to moveto second year.... If I reach my Scientist dreams one day I owe it to you man... I will come back in 5 years😍🥰
Why are you such an adorable little muffin, especially when you get excited ( like at 15:10 )? My poor heart shall do back flips at the joy that merries from your voice. If it's with you, if I can practice math with you, I won't drop out of college. Thank you.
22:59 in this problem, can we instead change the right side of the equation after changing the left so that it matches in the end? or will it be wrong because we already chose to do the left to make it equal to the right side? we can change the tan(x) to sinx/cosx and then multiply it to the sinx beside it. that makes it the same to the left side of the equation.
Proving Trig Identities do not have one approach. The goal is to prove the equality of the left and right sides. Therefore, as far as you are able to apply the identities and algebra to prove that the right side is equal to the left side, you should be ok.

Better keep watching during calculus subjects too, it helps alot

why is it such a broad range lol
E-learning was rough lol 😭😭😭
This in Trig has no reason to exist.
Thanks for being the best teacher ever ..on behalf of Africa 🌍
The Best EXPLANATION EVER. Not even my professor, explain like that. Thank you very much!
you deserve the world and more

This channel is my one stop for learning all I want 💜💜
Your a life saver man hope you help any other persons who's suffering from self study like me
This 25 minutes video is better than some wasted years of trying to understand these concepts. Thank u Mr Sir for shading more light on this.
Thank you so much for this, I actually have a Trigonometry Exam tomorrow. This has made things very vivid. 😩
Thanks for starting from the left hand side I understand it better
Man I wished I discovered you few years back. Keep up the good work.
the legend himself
probably because it was mediocre no offense
what an amazing video this is one of the hardest concepts i've learned thus far
MR. Organic Chemistry Tutor, thank you for a monster lecture on Verifying Trigonometric Identities in Trigonometry. These videos are fun to watch.
never knew this was a recent upload. shows how timeless his stuff is xD
That makes no sense
not gonna lie this was hard for me in class immediatly i watched ur vids it became simple! thanks so much!
Is this the same thing as *_"Proving"_* trigonometric identities?
yes
yes
THANK YOU!! My Precalc grade hasn’t been the best and I need to understand this to bring it up, and your practice has been SOO helpful! Thank you!! (Im gonna get that A- at the end of this marking period if it kills me lol)
O My God, you are truly The GOAT of making things simpler and easier to understand 💯, somebody give this dude an award🥳
this video has literally saved me in ap precalc thank you 😭😭🙏🙏
Would be appreciated if you did one about simplifying trig expressions. Been kinda confusing and difficult finding a way to rewrite problems while having no idea if I'm doing it right
Exactly. I totally agree
you are the boss i love it I am preparing for university and with this you boost my confidence thanks bro
My teacher made this look sooo complicated......
This guy makes it so easy.... 👏👏
Thanks so kindly Sir
you're really saving lives out here.
I have a really good teacher but I was out for exams and missed this stuff and got lost but this video got me up to pase for free thx so much I'm willing to pay next time I'm struggling
This Video is a lifesaver!! Thank you so much!! I've been struggling for a couple weeks now and your video explained everything I needed to know in easy to understand steps.
Thank you so much. I was literally revising the concepts from the old videos. You are doing a great job👍
For the last problem at 23:54 you can solve it quicker if you just convert tan(x) to sin(x) / cos(x) and then the top becomes sin^2(x) and you are done.
That's what I did!! Is it still correct???
@@lisakanzira6765 Yes! As long as both sides are equal in the end it is correct.
@@Hambxne YAYYYYY
I love you chemistry tutor. Verifying trig identities was really simple after watching this.
This was great thank you. Between math science guy and you now I understand trig identies/properties! Its actually fun its like a puzzle
I have a trig identity test today, feeling much more confident after watching this!
You are invited to my graduation party this weekend!
13:06
In question 5 it'd be easier if you take the more complex side of the equation and simplify it, I'm speaking this with prior experience and if you do that here is what you get:
Sin(x) Tan(x) = (1-cos²(x)) / cos(x)
=> Sin(x) Tan(x) = sin²(x)/cos(x) - since 1-cos²(x) = sin²(x)
=> Sin(x) Tan(x) = sin(x) × sin(x)/cos(x) - simplifying the square on sin(x)
=> Sin(x) Tan(x) = sin(x) × tan(x) - since sin(x)/cos(x) = tan(x)
Q.E.D
Really the best channel for studies.
Why is entry level math always so perfect like really all we have to do is follow a formula and always will get the answer
Thank God will open my mind till I know this topic
This video was very good. Thank you for your help.
By the way, I used to have a teacher who taught this lesson using analogies that don't make sense. She refers to factoring as "chopsticks and a bowl" and refers to multiplying by the conjugate as "chunky one". Weird right?
Im cooked 😭
me too 😅
Dude this whole subject feels like I’m throwing shit at a wall and seeing what sticks 😭
Thank you sir. I was lost until this video. Great job explaining it. Cheers!!!!
Thank you sir 😭u're my savior.
I have an exam is some minutes and I had no ideas how to solve this. N u just saved me.
Thank you very much. God bless u sir 😭🙏
I wish u a good life🌹
You have been great since the start of your channel.
Right when I needed it, thank you perfect timing
This was extremely helpful! Thanks so much
You know we all arrive few minutes before an exam and here I am The mighty Exam savior you deserve more than 20mil subscribers
I searched tons of videos for the pre requisite for this which is 7.1 (fundament identities) this is 7.2 what helped me was just practicing questions over and over, to me 7.1 is harder to grasp then 7.2. So to anybody reading this go practice 7.1 questions once you get to this it’ll be a lot more easier to understand
this is me 😅I couldn’t find his video on the topic of 7.1 so I skipped to 7.2 Ima go try 7.1 now I have a test in two days 😶
omggg, i'm so happy after this video. I've been so confuse bout those nonstop and now i finally understaanddd!!! thank youu!!

Mr. Organic Tutor i salute you and your skills in helping us. Thank you so much ❤️
THANK YOU, I was struggling so hard but then I used this as practice & I was able to finish my hw 😭

Delivered when needed the most...thanks again
lord bless and keep you bro 🙏🏻 i was COOKED for my test tomorrow. not anymore.

Only managed to answer 4 out of 46 trigonometry proof questions. Let's see my improvement after watching this video!
what happened? what you get!
The tutorial is very much helpful to students.keep up man.
Thank you. I don't know how to ask my teacher and your vids are so much helpful.
this helped me understand this so much better!! thank you☺️
My teacher didn't teach me this, so here I am. He's such a F+ teacher tbh
Proofs are the way to truly understand something in math
This is the first time I actually understood verifying
That 7th example something else man!!!

@@noahgodsonagbele7345 right. thanks!
Yeah I was wondering that too cuz I got sin^2/cosx = sin^2/cosx instead of the other way around
Thank you I've learned a lot today 🙃
AMEN to this! Helped me and my daughter!
This dude just saved me from failing my test😭😭
You are doing the lord's work.
this unit literally makes me wanna kms
What you are still uploading??? I’m impressed.
I think this was the first "test" I aced in a long time ;-;
Finally I’ve understood trigonometry
In example 8 i thought we just need to change tanx= sinx/cosx then multiply to sinx we have sinx^2/cos
that's viable, there are multiple paths for each one.
you can do that as a shortcut kinda way
I am glad to find this channel.It helped me a lot on my science subjects.May God bless you.
Wow 😯 thank you very much . I was stuck at trig identity equalities .
Trigonometry is very² hard I'm trying my best to understand this cause Tuesday will be our quiz
Your voice is heaven 😭
Calm down. Gross.
dunno man, seems kinda gay to me
If TOCT says "not an easy thing to do" you know it's gonna be insane
Im just 14 what did i do to deserve this
Nice to see you uploading again!
