OK I am confused. I am trying to do a lot of these and they just aren't making sense. I understand what Euler's Identitiy is saying but I don't know how to prove the other things. I am stuck on 50, 53, and 55a. Is there a relationship between cosine and sine I could use for 50. How many terms do I need to multiply together for 53?

  • I haven't done it yet, but for problem 50 it says to use equation 6:
For any real number $ \theta $
$ e^{i\theta} = \cos\theta + i\sin\theta $
I'm not sure how to use it though.
