triple integral of a sphere in cylindrical coordinates

Another useful coordinate system in three dimensions is the spherical coordinate system. It simplifies the evaluation of triple integrals over surfaces where cones. Note. In cylindrical coordinates, the equation r = a describes not just a circle in the xy-plane but an entire cylinder about the z-axis. The z- axis is given by r = 0.

In the previous section, we used cylindrical coordinates to help evalu- ate triple integrals. In this section we introduce a second coordinate system, called Triple integral in spherical coordinates (Sect. 15.6). Example. Use spherical coordinates to find the volume of the region outside the sphere ? = 2 cos(?) and TRIPLE INTEGRALS IN CYLINDRICAL AND SPHERICAL. COORDINATES. PROF. MICHAEL VANVALKENBURGH. 1. A Review of Double Integrals in Polar 1 dV . To compute this, we need to convert the triple integral to an iterated integral. We have to write both the integrand (z) and the solid of integration in spherical coordinates. We know that z in Cartesian coordinates is the same as ? cos ? in spherical coordinates, so the function we're integrating is ? cos ?. 1 dV . To compute this, we need to convert the triple integral to an iterated integral. We have to write both the integrand (z) and the solid of integration in spherical coordinates.
