- What are spherical coordinates?
- How do you compute triple integrals using spherical coordinates?
- What do the angles phi and theta represent in spherical coordinates?
- What does the length rho represent in spherical coordinates?
- How do you switch between spherical, cylindrical, and rectangular coordinates?
- What does the equation phi = pi/4 or phi = pi/2 look like?
- How do you know which order to write drho, dtheta, dphi when finding a triple integral?
- How do you find the surface area on a sphere of radius a using triple integrals and spherical coordinates?
- How do you find the volume of a portion of the unit sphere above z = 1/square root of 2?
- How can you find the gravitational force exerted by delta M at (x, y, z) on a mass m at the origin?
Spherical coordinates are introduced as a better way to find triple integrals of certain objects. The notation and the meaning of terms is described. Also, moving between spherical, cylindrical, and rectangular coordinates is explained. Many good examples are shown in this complex, but understandable lecture.
