## 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?

Hi there!

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

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

Hi all,

Do you know how one can ask Maple to show expressions involving special functions using their"classical symbols" instead of the associated Maple's command ?

Thanks !

Maple 2021

Hi, I am trying to enter into the Mini-Course Computer Algebra for Physicists from the help, but instead of going to the page I get the help page of Physics[FeynmanIntegral]. Can anyone confirm that this happens to them on Maple 2021.2?
