Thread: what is this called?

Here is my homework. The teacher explained it too fast, and I cannot find it in the book. Can anyone tell me what this is called so I can look up how to do it? Thanks!

Solving trigonometric equations.

And you will find dozens and dozens of these questions (with solutions) throughout MHF.

Hmm, OK thanks. I thought there would be something more specific, but I guess that's it.
