Hi all,

I have been trying to plot Riemann Zeta Function on certain range, but it takes a lot of time(several minutes ,maybe hours).These are the basic things.

How to speed up ploting Zeta?

The same problem with Optimization.

Mathematica ploting Zeta with 0.125 second and optimizing 3.42 second.Maple few hours maybe......




Hi everyone.

I'm trying to solve the following PDE


but I'm getting this error:

Error, (in pdsolve/numeric/process_IBCs) initial/boundary conditions can only contain derivatives which are normal to the boundary, got (D[1, 1](w))(x, 0)

The PDE represents the bending of a thin plate.
