Triple Integrals: Finding Limits Without Sketching

Click For Summary
SUMMARY

This discussion focuses on determining the limits of integration for triple integrals without the need for sketching the region. The user inquires about alternative methods to find these limits using given equations, specifically referencing the equation of a plane, x + y + z = C. The solution provided emphasizes that three points are sufficient to define a plane, allowing for the calculation of limits by setting two variables to zero and solving for the third. This approach streamlines the process of finding limits for iterated integrals.

Homework Statement



Here is a solved problem:

[PLAIN]http://img3.imageshack.us/img3/6948/97765276.gif

In part (e), they formulated the triple integral using the limits of integration they found by sketching the region. Is there a way we can find the limits of integration without sketching the region? To me, sketching this graph looks complicated, so I'm wondering if we can determine the limits for the iterated integral by just using the given equations...

The Attempt at a Solution



I appreciate any help. :smile:

Why would sketching a plane be complicated? 3 points are enough to determine a plane. So, for example, if you have some plane given with x + y + z = C, set x = y = 0 and find z, then set y = z = 0, and find x, and set x = z = 0, and find y.
