Trigonometric Identities Are Beautiful

Here is my response to Taylor's video on the beauty of mathematics

Teaching math is a skill, good job.

Thanks!

SOHCAHTOA !!

[calvinjaramillo]

ahahaha you should write that on the test.

[proffesor98]

can you prove this using a unit circle? anyone link me with it if so?

[LudgeONRS]

Fuck no they're not beautiful. They're a pain in the ass!!!

[TheRobinator143]

Lol this is way easier to prove using a trigonometric circle (and with the circle you can also calculate the sin, coc, tan and cotan of angles in a random triangle)

I'm in Germany right now and getting ready to take the ACT in April. THANK YOU for making this. Reviewing alone for this thing isn't so scary when you have such wonderful guides to follow. Vielen Dank :D

nice problem solving, now explain what sin2x+cos2x=1 means

[nero314100]

in your video you had text pop up saying "any right triangle", well, using the law of cosine's you dont need a right triangle as you know C^2=A^2-2AB(cos(c))+B^2 where A, B, and C are sides of the triangle and c is the angle opposite of the side C

good video =) maybe try speed things up a bit. too much time spent drawing etc

[ryantheleach]

awesome but get a better mic or filter your audio.

[brolly81]

thank god for people like this guy, for posting videos like this, to help people like me out with trig. I'm pretty good at math but have a hard time with trig at times.

Awesome video. 5 Stars!
