Question

How do you write the polar equations for `x^2+y^2=x`?

Answer 1

`r = costheta`

Explanation:

using the fact that `r^2 = x^2 + y^2 and x = rcostheta`

we can convert cartesian form to polar form.

`rArr r^2= rcostheta`

now , dividing both sides of the equation by r gives

`r^2/r =(rcostheta)/r`

`rArr r = costheta`
