Homework Statement
Evaluate [tex]\int\int\int[/tex] 1/[tex]\sqrt{x^{2}+y^{2}+z^{2}+3}[/tex] over boundary B, where B is the ball of radius 2 centered at the origin.
Homework Equations
Using spherical coordinates:
x=psin[tex]\Phi[/tex]cos[tex]\Theta[/tex]
y=psin[tex]\Phi[/tex]sin[tex]\Theta[/tex]
z=pcos[tex]\Phi[/tex]
Integral limits:
dp - [0,2]
d[tex]\Phi[/tex] - [0,[tex]\pi[/tex]]
d[tex]\Theta[/tex] - [0,2[tex]\pi[/tex]]
The Attempt at a Solution
I am just having trouble finding a good substitution for the integrand. When I substitute x,y, and z with the spherical substitutions, I just get a huge jumbled mess that I can't make any sense of.
