Answer 2

fine by me

Answer 3

Sort of. I should go to bed.

Answer 4

but can you anser this quickly! I gotaa go to bed To!

Answer 5

Not exactly about circles, but periodic motion, exponents in complex numbers, and trigonometric functions can all be modeled using parametric equations with circles.

Answer 6

umm i dont get any of that bro! I told u i have bad english!

Answer 7

I know, it's complex stuff. Let me try drawing a bit.

Answer 8

okay Thanks!

Answer 9

So that's the "unit circle"

Answer 10

Trigonometric functions can be modeled like this:

Answer 11

umm what grade are you ?

Answer 12

\[e ^{i x}= \cos x + i \sin x\] is Euler's equation, which comes from calculus (Fourier's techniques for infinite series, to be specific)

Answer 13

what grade are you!??!??!?!?!?!?!????!!!!!!!!!!!!!!!

Answer 14

I just realized, I said "complex stuff" and I just got in to complex numbers... accidental awful pun...

Answer 15

Oh, I left out periodic motion. OK, trig functions help with triangles, and periodic motion can also be modeled with sine and cosine. (sin and cos)
