You should write of what parts of the text were the most difficult to read, and to identify how many times a passage was read before some
understanding was achieved. Mathematical writing is often not immediately understood, and takes time and thought before comprehension.
1.Why would you use the chain rule?
2. What is the derivative of f(x) = cos (x4)?
3. What is the derivative of g(x) = (cos x)4?
4. Use implicit differentiation to find y’ of x2 + y2 = 8 at (2,2) and at (-2,2) (it may be helpful to look at the graph)
