You need to have those sin/cosine curves memorized. Do that now, flash cards work.

Draw them out now each on its own flashcard, and examine where both are positive.

You shouldn't have to ask this question, at your age.

Does theta represents a number?

If you have a scientific calculator, the cos and sin buttons are there for you to figure out this problem.
