Below we have links to plots either constructed by Wolfram Alpha or Maple (Maple graphs are shown as image files).

- Example from class, sphere with no parameterization
- Example from class, sphere with parameterization
- Example from class: y=x^2, for z between 0 and 1 (in Wolfram Alpha)
- Example from class: Cylinder y^2+z^2=4, in Wolfram Alpha
- Exercise 7
- Exercise 8. Here is another shot from below
- Exercise 9
- Exercise 10 (too much for Wolfram Alpha?
