@acer 

Thanks !
I am trying to add a custom palette, but it is yet not clear in Maple how to do this

@dharr 
Thanks!

It was only the(") what i  overlooked then.

@vv 

Thanks

Straightforward this without use of the VectorCalculus package

@acer 

Thanks

There is a vectorfield and the Gradient is graphed in this plot as a rootvector : is this correct ?
 

@rlopez 

Thanks

I am curious how this plot looks like : is there a example of this gradient vectorplot ?

@acer 

Thanks!

Great, now i can stay in the VectorCalculus package
 

@radaar 

Thanks

Never thought on this package 

I prefer the VectorCalculus package, because it is in the vector notation with the unitvectors

The with(Student[MultivariateCalculus]); version has interesting tutors
  

@Carl Love 

Thanks

The CD is from 1998 , yes for Maple V-4 and  want to learn more from vectorcalculus for using in partial differential equations

This error seems to be more difficult to solve

CH7B.mw
   

@Preben Alsholm 

Thanks

Got it now also working and i replaced " by % together with the (t)
Saved also from .mws (old) to .mw (new)
It are old worksheets and nowadays Maple has probably more to offer for easier visualising this topic ?
DYNAMIC DE plots 

The author has made a procedure for this 

@dharr 

Thanks

Don't get the worksheet  working yet unfortunately.

@Thomas Richard 

Thanks

I will look at it, what all new is and LinearAlgebraMigration is a help too

@Carl Love 
Thanks

I think  its a hopeless task , because matrix is written in capital letters in the old worksheets
So, i must restore this manual . .eh no with copy gifs ( much text ) 

Don't see another way 

@Mac Dude 

Thanks

There is no .mpl  extension as such in Maple V
I am afraid that this old sheets are not to restore for the current version of Maple

@Joe Riel 

Thanks

I made a mistake : It is the theory worksheet Dynamod.mws (now mw) you openened, but the answer worksheets are no complete anymore
I am not sure if the all theory worksheets are complete and also if all anwers worksheets are complete?
I think both two groups are missing text , pictures 

When i open them in Maple V-4 its all correct content

Uitw-03.mws

@Joe Riel 

Thanks

I did it again
