Question

Please help! Find the parametric representation of the curve
x^2 + y^2 = 25 and z=(1/pi)arctan(x/y)

needs to be in the form: x = x(t); y = y(t), z = z(t).

Answer 1

\[z = \frac{1}{\pi} \times \arctan(\frac{x}{y})\]

Answer 2

I'm wondering if that's what you mean

Answer 3

yes it is :)

Answer 4

I'll be back soon hopefully

Answer 5

thanks!

Answer 6

Okay, I am done, just need to post this

Answer 8

thanks a lot!

Answer 9

yw :D

Answer 10

Sorry Mya, I can't be like you and use Latex.

Answer 11

so if we use sin^2 t +cos^2 t =1 couldn't it also be y=5sint and x=cost and wouldn't this be a differrnt answer?
