Let Q be a bounded solid region in three space, and let f a function of three variables defined on Q. The triple integral integral of f over the solid region can defined in a manner similar to the definition of a double integral (see text). When f is the constant function 1, the triple integral gives us the volume of Q. Example: Let the region Q be the intersection of two right circular cylinders of radius one. The first is symmetric about the x-axis -- thus has equation 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.

The entry point is the lower limit and the exit point is the upper limit for the innermost (dz) integral -- these limits may be function of both x and y. 2) Project the solid Q onto the x-y plane and then use the rules for double integrals to determine the limits for for the outer two integrals in terms of this projected region R. That is , if using dx dy, then: a) Shoot a horizontal line through the projected region R. The entry and exit point for this line determine the lower and upper regions for the second integral (middle) which may depend on y. b) For the outer integral limits (dy), choose the min to max values of y that include the entire projected region.

Just as it is sometimes convenient to use polar coordinates when computing double integrals over appropriate regions, it is sometimes easier to use cylindrical coordinates to simplify the calculation of triple integrals. Recall that cylindrical coordinates and rectangular coordinates are just like polar coordinates, except we now have a z-coordinate which remains unchanged when converting between rectangular and cylindrical coordinates.
