## Homework Statement

I am trying to work through a trig review I found online, but this is the type of question I am needing to be able to solve. If anyone can be so kind to send me a link to a tutorial on how to solve these, I would REALLY appreciate it. Anyways, on to the question! :)

cos(2theta) = sin(theta), solve.

## The Attempt at a Solution

All I can think of is changing cos2theta so there is no more 2.

? What is the aim of a question like this, or this type of trig questions. ?
