Question

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

Answer 1

`r=(-3)/costheta`

Explanation:

Using the formula that converts `"cartesian " hArr" polar"`

`color(red)(|bar(ul(color(white)(a/a)color(black)(x=rcostheta)color(white)(a/a)|)))`

Substitute into equation

`rcostheta=-3rArrr=(-3)/costheta" in polar form"`
