Question

How do you convert x=y to polar form?

Answer 1

See below.

Explanation:

The pass equations are

`{(x = r cos theta),(y=r sintheta):}`

so `x = y -> rcostheta=rsintheta` or

`forall r ->costheta=sintheta->tantheta=1->theta = pi/4 + k pi`

so in polar coordinates

`{x=y} equiv {forall r, theta = pi/4}`
