# Polar Coordinates watch

1. Okay, so I know what I'm doing when you're trying to convert to Cartesian with r=sin(vita)

However, how do i go about it when you have r=sin2(vita)?

First use the identity

then multiply both sides by so you have and on the RHS.

Vita...? It’s theta.

You dont need to convert to Cartesian. It’s straight-forward doing it from the eq here.

It will start at 0, will increase to 3 as theta goes up to pi/4, then down to 0 as it goes to pi/2, and so on until 2pi

Good point. I didn't read the question properly and assumed the OP needed to convert to cartesian.

I feel like it’s more of a nightmare attempting to sketch from the actual Cartesian form without noticing a few things like symmetry.

Yes sketching using the cartesian form is definitely not the way to do this question.
