Hello, I am using maple 7 and I want to find all the solutions to a set of 4 equations with 4 variables.  These equations are all trigonometric.  fsolve of course only gives a single solution and using the avoid unction doesn't work.

I have tried to write something like this:

Sol1:=({equations},{vars})

Sol2:=({equations},{vars},avoid=Sol1)

and this always gives the same solution.  Any ideas?  Thank you.

Hey folks I have a question regarding how to fill an Array.

Lets say I do this...

Array(1..10, [seq(i, i=0..9)]);

This produces [0 1 2 3 4 5 6 7 8 9] as output which is fine.

Now lets say I want a 2x10 array (2 rows, 10 columns), the top row being the digits 0-9 (as above) and the second row being something else (in this case it is counting the number of times each digit appears in Pi)

I would like to use Maple to visualize some data produced by a computational geometry application I am working on.  However, my coordinate system is different than a standard cartesian system.  In my case, the positive Y direction is downward.

Can I re-orient the Y axis on a point plot to go downwards instead of upwards?

Hello,

Is there a way to export a file from Maple so that somebody without Maple can use ? My project is a dynamic one with components that need to be used by the "Reader".

Thanks,

Introduction to this blog

From time to time, I find some problem with Maple. It is not always Maple's bug, sometimes it is just my mistake.

I am used to use "Submit Software Change Request " form, but I dont know how to trace my requests (and I even dont exactly remember which bugs I posted). Thus, I decided to publish my troubles in this blog.

Unless stated otherwise, all the troubles I specify bellow are obtained on the Mac OS X 10.5 PPC platform using Maple 14.01 ...

What is the equivalent of

Shift+Tab = move the cursor to the previous region

on linux?? it is listed as working on windowns/macs but not on linux.

Also is there a way to customize keyboard shortucts? I am a vim user and navigating around a document in maple's gui is really painful (by the way I work in the "worksheet" mode)

thank you.

I try to solve the following, but it have the error of singular. can any one help me solve it.

> restart;
> dsys1 := diff(y(x), `$`(x, 2))+(lambda*lambda)*y(x) = 0;
              / d  / d      \\         2        
              |--- |--- y(x...

I have two expression like,

exp1:=A1*x*(k-p*x)+A2*x+A3*p+A4

exp2:=A5*x*(k-p*x)

where A1, A2, A3, A4 and A5 are some lengthy expressions.

I need to find the division of these two, namely exp3

exp3:=exp1/exp2

in the form

exp3:=(A1/A5)+the rest

In other words, I need to extract the part which could be normalized by x*(k-p*x).

I need to know how to use Maple to solve group permutaions and Cayley tables

I wanted that the same X-axe represents 1-10, 100-110 and 500-510. I do not know if it is possible to have a kind of X-values that in the same graph shows  the Y-values for the 32 following points: 1,2,..9,10,100,101,..110,500, 501,502,..., 510 . If I consider all interval 1-510, I could not be able to apreciate the graphic.

Thanks for your attention Kirnyk.

I'm trying to understand shooting method using maple in solving BVP. especially to solve boundary layer flow. I don't have any idea about the step size used and convergence criteria specified in shoot lib in the maple. Can anybody help me with this? Where can I refer to. Thank you

Could you give examples of differentiate differential form or integrate differential form using maple?

A friend asked me if Maple can do the following integral, since Mathematica just spins for an indefinite time with it:

int (  (1/sqrt(2*Pi))*(1/(1+exp(x)))*exp(-(1/2)*((x-a)/b)^2) ) from -infinity to infinity

Interesting integral though!

Dear friends,

The commands below generates a graphic. Hower I would like two things:

1. That the Y values are from 0 to 0.7 (in the example before it goes --by default--only until 0.5).

2. To represent in the X-axe the values from from 1-10, 100-110 and 500-510. I do mean, axe-X excluding 11 to 99, 111 to 499.

Here the commands:

restart:
ww:= [seq( [n, add(1/(n+1), k=ceil(1/3*n)..floor(2/3*n))], n=1..10)]:
plot(ww, style=point):

I have 2 sets of nonlinear motion equation for double pendulum problem. I wonder how can I solve these second order nonlinear equations first and second how can I extract the state space model for this system.

Thanks in advance
