Hey all,

I'm having trouble calculating a "workspace" volume.

The volume is easiest modeled by using spherical co-ordinates, and is defined by these boundaries:

(assume variables r, theta, phi)

[tex]\rho[/tex]: 1 to 1.1 meters

[tex]\theta[/tex]: 0.05 radians

[tex]\phi[/tex]: 0.1 radians

Here's how I've set up my integral:

Volume = [tex]\int^{1.1}_{1}\int^{0.05}_{0}\int^{0.1}_{0} \rho^2sin\theta \delta\phi \delta\theta \delta\rho[/tex]

I've used Pro/ENGINEER to give me the actual volume of this section: ~0.000595 m^3

But..that's not even close to what I'm getting when I solve that integral!

Anyone see where my problem is?

Thanks in advance~
