Obtain the solution of the diffusion equation,u(t,x)

a) satisfying the boundary conditions:

u(t,0)=u;_{1}, u(t,l)=u_{2}, u(0,x)=u_{1}+(u_{2}-u_{1})x/l+a.sin(n[tex]\pi[/tex]x/l)

b) in the semi-plane x > 0, withu(t,0)=u._{0}+a.sin([tex]\omega[/tex]t)

2. Relevant equations

Wish I knew...

3. The attempt at a solution

I haven't done none because I don't know where to start. I just want to ask what should I study to solve this problem. I have Riley's "Mathematical Methods for Physics and Engineering" and Zill's "Advanced Engineering Mathematics". If you have and can point me out the chapters, I would be much appreciated, or you can just tell me the subjects, that I'll try and look for them in the books.
