Quiz 1

I was able to get two copies of previous quizzes. The one from 2011 is missing the questions, but they seem consistent in the type of questions asked (just the details are changed). I had a hard time figuring out the trig identity from Question 2 \(\beta_{1s}\) - it is wrong (\(\cos3\psi\cos\psi-\sin3\psi\sin\psi = \cos4\psi\) not \(\cos2\psi\) (according to Wolfram Alpha).

Here are the links to the files:
