1. a) Find the value of e to thirty decimal places (count carefully!).
b) Graph sin2x, cos2x, and sin 2x on the same set of axes. One of these functions is the derivative of one of the others -- which are they?
c) Find
2. Describe (as if you were trying to convey it to someone over a telephone)

4. Find the exact values of the coordinates of the highest and lowest
place(s) on the graph of
.
5. Graph the formula you found in problem 5 of Problem Set 1. Describe (in English) the behavior of the graph for values of r which are large and values of r which are near zero. Explain how this makes sense for the physical situation being modeled.
