I'm having problems solving this problem although it should appear pretty straightfoward: (-l^2 - m^2 + n^2/(r + 0.016 z)^2) Z[z] + Z''[z] == 0 I am solving for Z[z]. These are the lines I use: DSolve[Above Equation, Z[z], z] I get an odd solution so I do a solution check plugging back in Z[z] and Z''[z] yet I don't get 0. In the above, l,m,n,r are all constants.
