1) Find the solutions of in the interval
I can determine that there are 4 solutions that need to be found, but I can only find 2 of them (). How do I find the others?
2) Find the period of the graph
I know how to find the period of functions containing either sin or cos, but not both. Can someone give me a crash course on how to do this?
Thanks in advance.
(Apologies for the choppy equation structure.)
