MaplePrimes Questions

Hello clever people,

Here's an easy question for you all I'm sure (though as a novice I've been stuck on this for hours).

Why is it that when I'm using Maple 12 some of my assignments don't seem to work while others do? Most of the time I don't have a problem assigning matricies and vectors but quite often Maple doesn't seem to want to recall the contents of a variable when performing operations.

Dear all,

     How can I insert mathematical notaions in Labels when plotting figures ?  I never encounter this problem, but now it is urgent for me to resolve it.  In labels, I depict the meaning of axes and need to use some mathematical notatioons.   If  someone  knows how to realize it , please inform me ASAP. Thank you very much ! 

Kindly regards,

Yours

Dear all,

I tried unsuccessfully to plot  (in 3D) in this solution using:
imax=10, mu=5, sigma=1.5
Could any one give me an help ?

Here is the maple code

imax:=10;

mu:=5; sigma:=1.5;

Im trying to use a symbol(phi) in a plot's legend, only instead of being displayed it shows %varphi; Is there anyway to force it to display the actual symbol? Thanks
Is this possible? Maybe some kind of option Ive been missing? Id like todo this to a couple of plots and would still like to see them on screen. Thanks

Hello everybody, I come form Denmark where i recently began at the local gymnasium(school).

Here i have math at the highest level possible and I have been told to buy a TI-89 titanium, but i would much rather like to use maple because it only costs half of what the TI-89 costs, and i already have a MacBook.

But the question is do any of you know any good books about the use of maple. Are there any down sides about using maple in comparison to using a TI-89.

Thanks in advance, Daniel Kristensen.

Hi,

 

this problem has been bugging me for quite some time now, and I have seen other people struggling with it as well.

When I work in Maple 11 and I want to insert a new section, he jumps all the way to the bottom and puts the new empty section there, where I don't want it to be.

I've also had similar things when I press the "T" to insert Text.

 

How can I solve this? Many thanks!

Hello,

 

It has been about 1 year since I have posted so I am a bit rusty.  I just uploaded a .mw file & thought I followed the instructions for creating a link to my file in the body of this message, but it doesn't look right & I would appreciate any pointers as to how I might do it right.

 

The reason for my post is that, as demonstrated in the uploaded file, I can't seem to get labelfont to work correctly.  When I include

font = [TIMES,BOLD,12]

it works fine but when I put in

Hello, I have an equation: y^2=4x^2 (My equation is more complicated. This is just an example) I want to define a function: f(x) = y1 - y2, where y1 and y2 are the roots of the equation in a descending order and then to plot f(x). I tried to do it as follows: S := (x) -> sort([solve(y^2 = 4*x^2, y)],`>`) C := (x) -> S(x)[1]-S(x)[2] plot(C(x), x = 0 .. 5) and I had an error "Error, (in S) invalid arguments to sort" When I remove the `>` option in "sort" it works.

Hi all,

I have been asked how a calculator works to calculate say exp(5) and did Maple use the same scheme.  I am sure it's a question of series but I am sure it's not a power series.  The question seemes stupid and I am ashamed for not knowing it but that's life.

Dear all

Can anyone suggest how the following code could run faster?

Hi

I've got an array A (size 20x3) whose elelments are plots

odw:=odeplot(q,[t,x(t)]):

A[1,1]:=display(odw):

etc

If I display(A); it prints very nicely to the screen. But when I try to print the plots on a row are all squashed up without being scaled equally in x and y and only the rows that can fit on a single page are plotted. I can export if as a gif file but thats a bit clunky. Is there no way to print directly from maple without it looking a mess?

 

thanks

Hi. I have some doubts about how to optimize a fortran very complicated output. I have an array called "stampa" that contain high order derivatives(very long expression). I create a fortran soubroutine for "stampa" with CodeGeneration with the following commands:

codegen[makeproc](stampa,[CS]);
codegen[optimize](%);
codegen[prep2trans](%);
codegen[split](%):
Fortran(%, optimize,defaulttype=numeric,deducetypes=false);

I have the following problems or doubts,:

I have a list of plots that I animate using dispaly command. I would like to know if it's possible to control the frame rate (fps) with a command, rather than having to use the GUI to set it every time I evaluate the worksheet. Any one know how to do this? Thanks.

Best regards!
