ok so my attempt at latex didnt work. any ideas why?
I have the heat equation
where -infinity< x <infinity
with u(x,0)=H(x) the heavyside function
and I'm looking for a solution of the form u(x, tau)=U(y) where y=x/sqrt of tau.
How do the boundary conditions become
I did something and got 1/0!! maybe limits are needed? Thanks for any help
