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.
