Hi. I'm not too good at maths and I'm having some trouble figuring out the basics of what to do with complex conjugates of functions. Our lecturer has set a couple problems requiring us to test if a few operators are Hermitian. Before I can get to those I thought I'd test the basic momentum...

begin by writing 1/c in terms of cartesian coordinates. c = sqrt[(x - x`)^2 + (y - y`)^2 + (z - z`)^2] 1/c = ? then differentiate using multiple applications of the chain rule. Remember that the primed terms are constant when differentiating respect to x, y or z. This was the part that...
