11-43.

Suppose you are given a graph of $r = f \left(θ\right)$ where $f$ is some function.

1. What equation would rotate the graph $90°$counter-clockwise?

$r = f(\theta-90º)=f(\theta-\frac{\pi}{2})$

2. What equation would rotate the graph $90°$ clockwise?

How is this answer going to be the same as and/or different from the answer to part (a)?
