The Maple commands for computing partial derivatives are `D`
and `diff`. The **Getting Started** worksheet has examples
of how to use these commands to compute partial derivatives.

- Compute the two first order partial derivatives and the three distinct second order partial derivatives of

at the point using the**diff**command and then again using the**D**command. - Given the function

- a)
- Plot the function and the plane on the same graph. Use plotting ranges , , .
- b)
- Find the derivative of in the plane .
- c)
- Graph the two-dimensional intersection of the plane . Be sure to use and ranges that are consistent with your ranges in part a. Does your two-dimensional graph look like the intersection from your three-dimensional graph?

- Given:

- a)
- Find the equation of the plane tangent to the surface at .
- b)
- Plot the surface and the tangent plane on the same graph over the intervals , .

- Given:

- a)
- Find all points on the graph where the tangent plane is horizontal.
- b)
- Find the equation of each horizontal plane and plot them on the same graph as the function . Use plotting ranges , .
