The Heat Equation:
The Attempt at a Solution
g(y) in the heat equation for this problem is e^3y. I'm having serious trouble solving this because my professor hasn't taught us the method, and it isn't in the book. I've considered trying a change of variables by taking z=x-y, but this has led me to nowhere. I am lost, and I am not just fishing for a result.
I actually want to know how to solve this damn thing. There's a few pages worth of **** in my notebook, and now I need some guidance.
Thank you for your time.
