Hello to all,
Lately this forum has become very helpful for me and by googling it I have found many answers to my questions, but unfortunately I could't find any help with this kind of diffusion equation:
w_{t}=a(w_{rr}+1/r w_{r})
I would like to hear some hints (or just helpful links), how it would be possible to get this solution:
w(r,t)=A+B/t Exp(-r^2/4at)
I have tried solving this equation by seperation of variables, but i guess it isn't the right method...
