Question: "How do I solve partial differential equation in Maple? it is that equation:

du/dt   = d2u/dr2 +  du/r*dr  +  u  +  f(r,t);     r=(0,...,2]; t(0,...,1]

also we have conditions:






I need to find u(r,t) and to graph it

r and t are cylindric coordinates.


f(r,t) is some definite function.



please help me , how to solve this equation. or may be show something similar to this equation. because I'm beginner in Maple, and don't know that to do...


Thanks beforehand
