deriving the double angle formulas

[@MisterThirsty311]

Sometimes you just need someone to talk you through it, thanks very much Mr. Taylor!

2:19 mind blown. Then my mind proceeded to remain blown for the rest of the video.

[@lesliemorales1209]

thank you! can you do a half angle video?

[@thomass554]

You are amazing sir

I thought this was John Cena talking

[@AR_BSME]

Still dont follow.
How cos2T has so many identities which i wasn't able to manipulate using the PT id.
Same for sin2T as well

[@hamade7997]

This helped a lot, thank you sir. Could you link the videos in which you explained the formulas sin(2A)=sin(A)cos(A) + cos(A)sin(A) and how you derived (cos(A))^2 - (sin(A))^2= (cos(2A))^2?
All formulas you derived came from these two (except the tangens one I believe) so I was wondering how you came you came up with these?
Great help, thanks.

What an awesome and sincere comment!

[@amuriatdeogracious5371]

Sin(A+A)=Cos(2A)

[@amuriatdeogracious5371]

Sorry I meant Sin(A+A)=sin2A

[@alinnanibay8398]

the thing that is most confusing about trigonometric identities is you don't know which one is correct or when to stop :(

[@nochannelvideos]

Thank you so much.. this was very helpful !

helped me a lot thank you very very much

[@thisguy916]

why couldn't my trig teacher have just taught it this way instead of forcing me to memorize an endless amount of formulas?

[@calvinbarajas5144]

Amazing stuff. Thank you so much.
