Triple Integration: Evaluating by Changing Order of Integral

Click For Summary
SUMMARY

The discussion focuses on evaluating the integral ∫∫∫ ze^(-y²-z²) dz dy dx by changing the order of integration. The original limits are z from 0 to ∞, y from x/6 to 3, and x from 0 to 18. The proposed new order of integration is ∫∫∫ ze^(-y²-z²) dy dx dz, with limits adjusted to z from 0 to ∞, y from 0 to 3, and x from 6y to 18. The community emphasizes the importance of clarity regarding whether the provided integral is the original problem or the attempted solution.

Homework Statement


Evaluate the integral by changing the order of the integration in an appropriate way.

∫∫∫ ze-(y2+z2)dzdydx
z goes from 0 to ∞, y goes from x/6 to 3, x goes from 0 to 18


Homework Equations





The Attempt at a Solution


to change the integration
∫∫∫ ze-(y2+z2)dydxdz

z goes from 0 to ∞, y goes from 0 to 3, x goes from 6y to 18

I'm not sure if this is right, so if anyone could steer me in the right direction that would be very nice, thanks in advance.

I am not sure what you are saying. You say the problem is to change the order of integration so you can do the integral, you give an integral and say you are not sure if that is correct. Is what you give the original problem or your answer? If it is your answer, we cannot say if it is correct or not without seeing the original problem. If it is the original problem- it is integrable just as it stands.
