I'm Trying to calculate the Determinant of a 3 x 3 Matrix with symbolic entries with maple 15. But the Determinat function gives a wrong result. From the C+A-1 expression it uses only the C and ignores the rest.

When I calculate it "manually" the result is correct.

Here is what I'm doing:

The Maple file is attached to this question.

arclengthproblem.mw

When a try approximating this problem by five decimal places, it doesn't do it. How do you fix this?

Please, consider this example:

I wonder why the match function returns TRUE and expressions that depend on the main variable x. I hope that someone can give me an explanation.

Hello everyone.

When exporting the model in the picture, I want the variables to be:

s_P2(t), theta_R2(t) and theta_R3(t), as in the help example.

http://www.maplesoft.com/support/help/MapleSim/view.aspx?path=MapleSim/Multibody/Kinematic_Exports

However, I obtain:

theta_R1(t), theta_R2(t) and theta_R3(t)

How can I choose the variables that I want?

Thanks for make learning easier!

Is there any way for maple to compute the nth degree taylor polynomial?
I tried using taylor(f(x),x=0,n) but that gave me an error. So then I tried taylor(f(x),x=0,infinity) but that just ended up giving me a memory error. Any help?

I have simulated 50 trajectories of an ODE system, with  a command roughly like this:

myPlot :=
 seq( plots:-odeplot
    ( Sol(i)
    , [ u(t), r(t), q(t) ]
    , t = T .. 0                          ### Time Run Backwards
    , 'numpoints' = 2*abs(T)
    )

I need to solve an optimization problem. Please offer your insights.

Suppose there are two functions (my case is more complicated than this example).

f(x,y)=x-y, 0<x<1, 0<y<1

g(x,y)=x*y, 0<x<1, 0<y<1

The goal is to get the maximum values for f(x,y) and g(x,y). However, it is not simultaneous, but sequential. In the first stage, only x can be chosen to maximize f(x,y); in the second stage only y can be chosen to maximize g(x,y...

Hi,

I have n second order differential algebriac equations (symbolic). I need to convert this system to [A]{X''} + [B]{X'} + [C]{x} + D =0,  where X is the column vector containg the variables and A,B,C,D are the coefficent matrices of X'', X',X and the constant term matrix respectively.

Is there a way to generate this matrices in Maple?

Thanks.

Giving a expression as follows, how to extract  powers of g to a list?

 In this example the list of powers of g is {2,1,2}

Hi all,

      i am new to maple before getting this software i need to know how it works in order know that i want trial version of maple software how to get this trial version please suggest me some idea...

I have one 2d and one 3d animation that I want to play at the same time.

p1:=animate(sphereplot, [exp(6*sin(t))-1, theta=0..2*Pi, phi=0..Pi], t=0..3, frames=100):
p2:=animatecurve(rhs(sDE), t=0..3, frames=100):
display({p1, p2});
Error, (in plots:-display) cannot display 2-D and 3-D plots together

I also tried using:

p2:=animate(implicitplot,[(i)^2 + (j)^2= (rhs(EQ2))^2,
                               i = -exp(6)..exp(6),
                               j = -exp(6...

test.zip

1) Compile under vc express 2010 debug config. Don't forget point out your location of maplec.lib in configuration properties/Linker/General/Additional library directories. Assure that configuration is at least Debug or all.

2) Run sheet test_bombard.mw from Debug directory.

Have permanent crash on BombardByRandoms call. If i would transmit creating of rtable from 'InitInternal'...

I've just registered my copy of maple and I'm trying to figure out how to use it to find the arc length of a curve on a given integral. My function is: upper limit 0, lower limit -3; and after the integral sign, the square root of 1+4x^2 dx.

Hi,

I have a pretty simple problem. Given the following set of responses to a "yes (y)/no (n)" question, create a pie chart and a bar chart.

y, y, n, n, n, y, y, n, n, n, y, y 

I would like solution that does not involve coding the data, say y = 1 and n = 0. I am aware of the BarChart and ColumnChart commands in the Statistics package, but I can't seem to get them to work with nonnumeric data. Is there an easy way to do this?

Hello,

I downloaded the Modelica_Fluid 1.0 Library from the Modelica website. When I try to import this library into MapleSim5 I get the following error:

Duplicate class definition found for Modelica_Fluid.Pipes.BaseClasses.WallFriction.Detailed.msim/UNKNOWN

I then click "ok" and the importing stops working with the last message being:

Querying Modelica classes...

Can anybody offer help with this?
