You can copy the worksheet now, but you should read through the lab
before you load it into Maple. Once you have read to the exercises,
start up Maple, load
the worksheet `Coords_start.mws`, and go through it
carefully. Then you can start working on the exercises.

To change to cylindrical coordinates from rectangular coordinates use the conversion:

To change to spherical coordinates from rectangular coordinates use the conversion:

Using a triple integral to find the volume of a solid translates in the following manner:

- Given the rectangular equation for a circular cone:

**A)**- Graph the equation using the domain values of , and the range values .
**B)**- Write the equation in cylindrical coordinates and then graph the equation.
**C)**- Write the equation in spherical coordinates and graph it.
**D)**- Use the simplest of the three coordinate systems and a triple integral to find the volume of a right circular cone of height .

- Now suppose an icecream cone is bounded below by the same equation of the cone given in exercise 1 and bounded above by the sphere . Plot the icecream cone using rectangular coordinates over the same intervals as exercise 1a. Find the volume of the icecream cone using spherical coordinates.
