Homework Statement
Assume that f(x,y,z) is a continuous function. Let U be the region inside the cone z=√x^2+y^2 for 2≤x≤7. Set up the intregal ∫f(x,y,z)dV over U using cartesian, spherical, and cylindrical coordinates.
Homework Equations
CYLINDRICAL COORDINATES
- x=rcosθ
- y=rsinθ
- z=z
SPHERICAL COORDINATES
- ρ^2 =x^2 + y^2 + z^2
- x = ρsin(phi)cos(θ)
- y=ρsin(phi)sin(θ)
- z=ρcos(phi)
The Attempt at a Solution
Do Ineed to have a function for the inner two integrals?
For my limits on integration for Cartesian coordinates are
z = x^2 + y^2 -4 and z = x^2 + y^2 -25
I DON'T KNOW FOR X
and y = 2 and y = 5
For my limits on the spherical coordinates are
θ=2π, θ=0; and ρ=2, ρ=5
I DON'T KNOW IF WHAT I'M DOING IS RIGHT OR NOT. I'M LOST :(
Please and thank you for your help!
