Homework Statement

The Attempt at a Solution
This is from a physics course and I'm not taking the calc co-requisite yet so I'm trying to get by on what I can teach myself, which is inadequate for this task apparently. I don't understand the process of getting [itex]sin\theta[/itex] out of [itex](1-cos\theta)[/itex]
