Question about Laplace operator

Question

There was a question on my homework today:

 

Work out the formula for the Laplace operator in polar coordinates.

 

How do I do with this question?

Answer 1

Hi Khanh,

 

It is a little bit difficult to explain without having a tutoring session. You need to convert the differential operators in cartesian coordinate to the corresponding form in the polar coordinates. Let me know if you are interested in getting further explanation through an online session.

 

Thanks.
