## Homework Statement

Convert the following Cartesian equation to polar form.

x^2/9 + y^2/4 = 1

## Homework Equations

r*cos(t)=x

r*sin(t)=y

r=Sqrt(x^2 + y^2)

y/x = Arctan(t)

## The Attempt at a Solution

I get ugly looking things like r^2(cos^2(t)/9 + sin^2(t)/4) = 1 but being a simple ellipse (edit: duh) I expect a cleaner answer.
