Convert the following equation given in polar coordinates to Cartesian (x,y) coordinates where y = ?? Have no idea how to start this..with polar coordinates..can someone help?

Have no idea how to start this..with polar coordinates..can someone help? You're expected to know that $\displaystyle x = r\cos{\theta}, y = r\sin{\theta}$ and $\displaystyle r^2 = x^2 + y^2$. How do you think you can rearrange this formula so that it is in terms of $\displaystyle r, \sin{\theta}$ and $\displaystyle \cos{\theta}$?
I solved it and for the answer I got y=x^2...is that right?
