Hi all, my question is essentially the title.

**I would like to find the polar coordinates for the Laplace of a particular scalar function.**
My question is attached here, if me attaching the image did not work then I will try and drag and drop the image.

Here is the link of the question:

Laplace from a scalar function - Album on Imgur
Now my working out for this is here, although I am not entirely sure it is correct.

Again here is the link and the image?

I would really appreciate if anyone can help me out here.
