My question entails the laplacian of a scalar function and I would like to express it in polar coordinates.
Stuck on whether I am supposed to use one of the forms of Laplace's equation to help me solve or do something else.
Any advice/guidance/help would be warmly appreciated.

Well there are harder stuff than this.
Anyway, you have $\nabla^2 f = \nabla \cdot \nabla f = 1/r\partial_r (r\partial_r f)+1/r \partial_\theta (1/r \partial_\theta f)$.
Straightforward, plug the second identity to the first.
