Question

Flux Integral question:

Why are the bounds of integration for dz in this problem what they are?

Answer 1

It makes sense to me that z=o is the bottom bound, given the xy-plane is specified. My question is, why is the top \[\frac{ 1 }{ 2 } (20-3\cos \theta - 3\sin \theta)\]

Answer 2

When I convert cylindric coordinates, and solve for z I get : \[3z = 20 - 3\cos \theta - 3\sin \theta \]

so \[z = 1/3 (20- 3\cos \theta - 3\sin \theta)\]

Answer 3

Any suggestions? I doubt this is a typo, I am more likely just doing something wrong, but no idea what.

Answer 4

hiii :)
