i have a pde where i want to be able to manipulate variables to see how the function acts. The problem is that i don't know how to set boundry conditions or g=graph the square of the function. The function should be: (k is a constant)
DuDt = k*(DuDx)/Dx + (x^2)*u
with an initial condition:(b and s are constants)
u0=e^[(x-b)^2/s]
and boundary conditions
u(-5,t)=0 u(5,t)=0
any help would be very much appreciated
