Trig Identities

This trigonometry video tutorial discusses common trig identities and formulas such as the pythagorean identites, reciprocal identites, quotient identities, even odd identities, cofunction identities, double angle formulas, half angle formulas, sum and difference identities, power reducing formlas, product to sum identities, and sum to product identities.

This the day I realized it wasn't all sunshine and rainbows😭🙏

[Naturo_ukuzami]

This man literally has tutorials on every topic I want

[twa]

The Organic Chemistry Tutor reigns supreme

[sasugamegami]

Bro teaches physics, algebra, chemistry, trig, basics of math, matrices, calculus, etc. What does this man can't do in the field of math?

[caviwhy]

couldnt be even more perfect, literally learned about trig identities in class today and didnt understand it. immaculate timing

[Pugsgunsandstuff]

Fought the whole semester to keep my A, this is what's going to blow it for me. This stuff makes absolutely zero sense without a reference sheet or something.

Bro literally my teacher only talks about donkeys in class. I mean literal donkeys. And yet I’m supposed to know this? This man has SAVED me

[Eeppydeepy]

Thanks, man. Been cramming right before finals trying to relearn everything, and this channel has been a life saver. Everything is explained so clearly and simply it makes trig seem easy.

This channel is by far my favorite YouTube channel to learn Math. Thanks for making these videos. I can only imagine the hours and effort you put in.

30, 60, 90 and 45, 45, 90. The good ol' Right triangle basics. Your channel helped me out quite a bit in my trig class.

[friedhegg]

bruh literally two minutes in and you already gave me the best way to remember sin, cos, and tan. wow ur a legend

[ashistoxic]

the timing of this video is actually perfect. I have a test tomorrow and I need to know my trig identities,

[fwoopp]

Babe wake up, The Organic Chemistry Tutor dropped a new banger

[gamereplixer]

I have a trig exam on this exact content tomorrow, big praise.

I studied all this with great interest while studying in college. But now after 13 years it was very difficult to recollect. So when I go for an interview for the position of a mathematic teacher to answer the trigonometric functions was a difficult task. But this video helped me to remember all the trigonometric functions. It is really helpful for me. Thank you so much.

[dakamary]

Though my test was on Monday, your previous video for trig identities helped, I'll make sure to watch this one too

[ryvmdqj]

thank you for explaining this chapter in a very systematic way, it really helps!

[fidelisikhifa]

Thank you so much. You made me to conquered my fears. Thank you so much. You broken a complex maths into parts for my understanding. I appreciate you.

[badoibaboi]

how do u know when to apply a trig identity? is it necessary to apply an identity everytime u see one, or are there times where leaving the trig expression just as it is is better than applying an identity?

[Turboner]

Bro right after my trig unit just ended. But I got the pre-calc final. Thanks for uploading! You da man. Wish me luck!
