Hello,

I'm new at maple and I was wondering if someone could help me. I've got a function with 3 variables:

v1'=(v1*sqrt((1+u)^2-4*u*cos(b)^2))/(1+u)

Can you plot this function? Or do I have to give one or two variables a value and plot the function 3 different times with just one variable?

Thanks

I was trying to use the LeviCivita in the physics package to type the left side of the following equation and let maple compute the right side, where it considers the totally antisymmetric tensor identity which reduces to 4 Kronckers. Then the Kroneckers disappear and give rise to the right hand side. But I don't know how to tell maple to do this. There is also another Levi_Civita command in the tensor package.

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.

Best, Henning

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.
