## Riemann Zeta function - Problems with P...

Maple 2015

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 don't have this such problems.

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

## PDE - bending of thin plate...

Maple

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.

## Dsolve with parameter...

Maple 2015

Hi every body.

I want to solve a differential equation:

ode=D(r(θ),θ).....

I have the initial conditions:

e=10^(-20)

r(e)=A where A is parameter.
r'(e)=0

sol:=dsolve({ode,r(e)=A,D(r)(e)=0},parameter=[A],numeric)

and:

All in the file.
