Question

How do you convert `x = -3` into polar form?

Answer 1

In polar form equation is `r=-3/costheta`

Explanation:

If a point `(x,y)` is written as `(r,theta)` in polar coordinates, then `x=rostheta` and `y=rsintheta`.

As such in polar form equation `x=-3` can be written as

`rcostheta=-3`

or `r=-3/costheta`
