How to create my own symbolic notation f...

Maple

Hi !

I want to create a notation for a function, let's say :

f:=(x,y,z)->something

such that when I ask for

f(x,y,z)

Maple returns

fx,y(z) or anyother "nicer view" of that expression.

This is (I think) a similar action of replacing BesselJ(n,x) by Jn(x).

What is the difference between Physics:-...

Maple

Hi all,

I am working with the physics package and I want to know if there is a difference between Physics:-CompactDisplay and PDEtools:-declare ?

As well as the difference between Physics:-Simplify and simplify.

For both cases, can they be used as the same ? Are they incompatible in some case?

Thanks !

PDEtools declare but still using the sta...

Maple

I want to know if it is possible to use the declare command from the PDETools package for a function

f(x,y,z)

and still, having the notation $\frac{\partial f}{\partial x}$ instead of $f_x$ for the Maple command %diff(f(x,y,z),x)

Thanks !

How to enter the fluid convective term u...

Maple 2022

Dear all,

I'm trying to enter an equation (Navier-Stokes) in Maple using the Physics[Vectors] package. I am having trouble with the term

$(u\cdot \nabla) u$

but Maple returns an error when entering the commands :

( u_(t,x,y,z) . %Nabla) u_(t,x,y,z)

I tried other combinations of this without success, like :

( u_(t,x,y,z) . %Nabla)(u_(t,x,y,z))

( u_(t,x,y,z) %. %Nabla) u_(t,x,y,z)

( u_(t,x,y,z) %. %Nabla) (u_(t,x,y,z))

Could you please give me some help with this?

New in Maple 2022...

Hi there!

Do you know when the new version of Maple will be released?

Do you think it might come with a "Dark Theme"?

Regards

Kevin
