## Question:

Suppose {eq}f(x, y, z)=\frac{1}{\sqrt {x^{2} + y^{2} +z^{2}}} {/eq} and W is the bottom half of a sphere of radius 3. Enter {eq}\rho {/eq} as rho {eq}\phi {/eq} as phi, and {eq}\theta {/eq} as theta. As a elated integral {eq}\int \int \oint_{w} f d v = \oint^{B}_{A} \oint^{D}_{C} \oint^{F}_{E} \: d \rho \ d \pi \ d \theta {/eq} with limits of integration

A.=

B.=

C.=

D.=

E.=

F. =

Evaluate the integral.

## Spherical Coordinates:

The spherical coordinates are especially useful when we calculate the integral for spheres centered on the origin.

In this case, all integration variables vary between constant values.

Taking into account the set can be expressed in spherical coordinates as:

In this lesson, we introduce two coordinate systems that are useful alternatives to Cartesian coordinates in three dimensions. Both cylindrical and spherical coordinates use angles to specify the locations of points, a feature they share with 2-D polar coordinates.
