I understand I would need the Dirac delta function, what I don't quite understand is your solution method. What would ##A(x)## represent? Also, as I have mentioned before, what you name ## f(x,y) ## is actually zero once I calculate the laplacian, so I will be left with just the expresion ##...

Homework Statement Find the distribution of charge giving rise to an electric field whose potential is $$\Phi (x,y) = 2~tan^{-1}(\frac{1+x}{y}) + 2~tan^{-1}(\frac{1-x}{y})$$where x and y are Cartesian coordinates. Such a distribution is called a two-dimensional one since it does not depend on...

Hello PF, I'm lorentzian and I'm a physics undergrad from Mexico. My current interests are statistical mechanics and a little bit of computer science. I would like to find a research group that focuses on Biophysics so I could apply some statistical mechanics to that.
