represents a point in cylindrical coordinates. The first two
variables are polar with our third variable being our regular z variable. This coordinate system can represent some
surfaces in a compact form. This coordinate system will be very useful when we have a solid that has a circular
projection in the xyplane. But realize the projection does not always have to be in the xyplane. Once you find which
plane has a circular projection then those two variables are rewritten in polar while the third variable remains the
same. Not only does it make it easier to work with the limits for your triple integral but it can make a triple integral that
can’t be solved analytically in the rectangular coordinate system into one that can be solved in the cylindrical system. Here is an example where the polar part is in a different plane: Example: Example: Summary of Section 13.6
1 Sketch the solid represented by a triple integral that is in cylindrical coordinates 2 Sketch the solid represented by a triple integral given in the form: dy r dr d or dx r dr d 3 Set up and evaluate a triple integral with cylindrical coordinates 4 Set up and evaluate a triple integral in the form: dy r dr d or dx r dr d 5 Convert a triple integral from rectangular coordinates to cylindrical coordinates Section 13.7 Spherical Coordinates
These coordinates were introduced at the end of chapter...
