HI ALEX,

I have been presented with the following problem: Find the Triple integral of a cube in spherical coordinates defined by the intersection of the following planes: x= plus or minus 1/2; y= plus or minus 1/2; z=plus or minus 1/2

My initial attempt was to trisect the cube that resides in the first octant, multiply it by 24, and hopefully get an answer of 1. The limits of integration I used for theta, phi, and rho are the following:

0 < theta < Pi/4

Pi/4 < phi < Pi/2

0 < rho < (sec (theta)*csc(phi))/2

However this didn't work. I get an answer of 1.14 . . . . with Maple V.

Could you tell me what wrong?

Thanks in advance,

Emerick
