Finite Difference

[SFares]

Hello,

I am trying to do a finite difference to solve the differential equation and compare it with the analytical solution. I am not sure why I am not getting the plots to work out. I attached both Mathcad-15 and Prime 7 files. I converted 15 to Prime7.

Thank you,

Sam
