How to simplify calculations?...

Asked by: spalinowy 30

August 02 2017

0 0

I have a very large set of equations that calculates for a long time. Up until now, I have designated the second derivatives and copied the finished equation to another program to do the simulation. But with this file I can hardly do anything because the equations are too long. Even saving a file after computation is not easy. Export to PDF takes 20 minutes and the file has 120 MB and 1000 pages. Recording to .mw has not gone yet due to the occurrence of a write error message. I have 16 GB of RAM and after calculation is 14 GB in use.

Conformal Plot mapping function...

I was wondering if it were possible to call only the mapping function used to grahically display using a particular plot command in general, but aside from that, this is the one in specific id really like, naturally, since thats a bit of a hole in the understanding of what you are looking at thats probably important in some way to something.

Is there an example where the NO_INT option in inv...

Asked by: Preben Alsholm 13471

July 30 2017

1 1

In the help page for invlaplace we find the statement
"If the option opt is set to 'NO_INT', then the program will not resort to integration of the original problem if all other methods fail. This will increase the speed at which the transform will run."

This statement is found in Maple 2017 and in Maple 8 and I believe in all versions in between.
Can anyone provide an example of a function F(s), where
invlaplace( F(s) ,s, t, NO_INT);
gives a different result (or works faster) than
invlaplace( F(s) ,s, t);
?
## It should be added that an identical statement is made in the help page for laplace itself.

salute ! all Maplesoft managers and employee programers ...

Is there any fortune in near future to have some kind of machin based "Proof Assistant" as built in part of Maple IDE ?

it can be better than COQ ?

also there is a great lack of user interactivity by Geometry and Geometry3d packages of maple !!!

for example most of the time it is nessesary (and more facilated) to define geometrical primitive shapes manually or making simple transformations and dissectings attaching ... rather than doing them programaticaly or by commands ?

even having traditional tools like compass ruler ... in pallettes of Geometry window ?

integrals, series and products...

Asked by: J F Ogilvie 263

July 25 2017

A few days ago I was browsing through some books in my collection, that by Gradshteyn and Ryzhik in particular. What fraction of the intregrals, series and products therein can Maple handle correctly? Besides special functions these properties are valuable components of symbolic mathematical software. If the answer to this question is not nearly everything in that printed compilation, this inclusion in Maple is a worthy objective.
