(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

f = r^-n-1 * cos(n+1) θ satisfies laplace's equation.

r^2 [itex]\partial^2 f / \partial r^2[/itex] + r[itex] \partial f / \partial r[/itex] + [itex]\partial^2 f / \partial θ^2[/itex] = 0

2. Relevant equations

P.D.E

3. The attempt at a solution

[itex]\partial f / \partial r[/itex] = nr^n-1 * sin (nθ)

[itex]\partial f/ \partial θ [/itex] = ncos(nθ)*r^n

Are these derivatives right ?
