Thanks :)

How does one show that z^{1/3} is not unique in the complex plane? [ Similarly for z^(1/2) and ln(Z) ] Thanks, Daniel

I would appreciate hints on how one can calculate the dependence of the electric potential as a function of distance r from an isolated charge Q in 5-dimensions

I have got the answer #(x,t) = e^-((x-ct)^2) Am i right?

Yes, sorry to be confusing but your assumptions were right... The initial conditions are #(x,0) = e^(-x^2) and #'(x,0) = 2cxe^(-x^2)... I wasn't sure how to use these to get to the solution but it seems like i need to solve those two equations. Thanks!

I have to solve the 1-dimensional wave equation using D'Alembert's solution. I know the solution has the forum 1/2[f(x-ct) + f(x+ct)] + 1/2C*integral(g(s)ds) and i have two intial conditions f(x) and g(x)... do i just plug in (x-ct) where i see x etc...? also what is g(s) in the...

How can they have any energy if the amount of energy in the universe is fixed?
