1. More Polar Equations

Transform each polar equation to an equation in retangular coordinates.

(1) r cos (theta) = 4

(2) s rin (theta) = -2

2. These are very easy, you should know that $\displaystyle r \cos \theta = x$ and $\displaystyle r \sin \theta = y$

3. can you...

Can you do the first one and show me the steps? I will then be able to take it from there.
