## Homework Statement

Find all points of intersection of the given curve.

## Homework Equations

r = 1 - cos θ, r = 1 + sin θ

## The Attempt at a Solution

1 - cos θ = 1 + sin θ

1 = 1 + sin θ + cos θ

0 = sin θ + cos θ

After that step, I blank out and can't think about how to get any further on just looking for θ = ?
