## Solving a PDE analytically with a bounda...

Maple 2022

I wanted to solve a pde of two variables in spherical coordinates with a boundary condition at a specific radius. I am doing something wrong because the pdsolve just evaluates for several minutes and does not actually give anything.

Could someone have a look and let me know what I am doing wrong.

## Help with 3d plot in polar/sphericalcoor...

Maple

Hi,
I wanted to do a 3d plot such that a function is plotted over a polar plane. I am not sure what is the best way to plot this and would appreciate some guidance/tips.

I want to plot the following function 1/(r^2*sin(theta)^2) .

I tried plot3d but the base plane is not a circle but a square...

## Benchmarking script/package for maple?...

Maple

Mathematica has a benchmarking package that allows you to evaluate your computer's performance with respect to other computers with different specs.
I was wondering if there was a similar script/package for maple?

## Solving pdes with multiple functions....

Maple

Given a pde (or a set of pdes) of multiple funcitons, is there a way to look for solutions when one of the functions is kept arbritary.

For example if I have a set of pdes with f1,f2,f3. Is there a way to see if there is a functional form for f2 and f3 such that the equation is satisfied for any f1?

## Setting spacetime indices 0,1,2,3 instea...

Maple

Is there a way in the physics package to get my index to run from 0 to 3 instead of 1 to 4/0?
