Maplesim 7.0(1) installer looks for Maple 18 installation.  Will Maplesim work with Maple 2015?

If not, what is the expected date of making both products compatible?

Hi all, I want the best for you.

I really have confused with this bad integral (HeunB)which I've got it 2 weeks ago from a solution by Maple 17. I should solve this one to solve the derivative of this too.

Help me please, I attached the attribute file.

Regards.

Hi all,

It's been a while since I have used Maple. To be honest I haven't used it for over six years.

I am trying to solve simple differential equations, however I have many issues.

I am trying to simulate what author of this paper did 06421188.pdf

My file looks like this (Pendulum.mw)

Can someone help me to simulate this system? I simply can't remember how to do it.

Cheers,

Bart

Attached is a photo with the code I am working for.  

On the top is practice code with a simpler ODE to help with trouble shooting, on the bottom is the ODE I am working with.

I was hoping to gain insight about the _z1 symbol in the solution, I haven't been able to find much help on other threads.  I would like to know how I can go about working with it - if it is something on my end or if it is the nature of the equation I am working with.

Thank you for any help,

Josh

I have a nice procedure that is as follows, that explores the behaviour of a mapping in R^2.

InversePoincare := proc (v) options operator, arrow; v*Norm(v, 2)/(1-Norm(v, 2)^2) end proc

SphereVectorPlot := proc (T, radius, radiusIncrements, angleIncrements, lengthParam)
local listOfPairs;
listOfPairs := {seq(seq([[radius*r*cos(2*angle*Pi/angleIncrements)/radiusIncrements, radius*r*sin(2*angle*Pi/angleIncrements)/radiusIncrements], T(InversePoincare(`<,>`(radius*r*cos(2*angle*Pi/angleIncrements)/radiusIncrements, radius*r*sin(2*angle*Pi/angleIncrements)/radiusIncrements)))-InversePoincare(`<,>`(radius*r*cos(2*angle*Pi/angleIncrements)/radiusIncrements, radius*r*sin(2*angle*Pi/angleIncrements)/radiusIncrements))], r = 0 .. radiusIncrements), angle = 0 .. angleIncrements)};
if lengthParam = false then
 return arrow(listOfPairs, scaling = constrained, shape = arrow)
else
 return arrow(listOfPairs, length = lengthParam, scaling = constrained, shape = arrow)
end if
end proc

Essentially, we plot vectors v at location u. Since the vectors v in general vary wildly in magnitude, I would like to visualize the magnitude change by using color and/or transparency, preferably the latter. Is it possible to do so, and if so, how?

Hello,

I have modeled a slidercrank with absolute coordinates.

I have a slight problem when I want to mesure the Euler angles with Euler angle sensors.

In fact, the angle of the crank around the z axis (gamma1) always stay betwen -pi and pi. I would have like to see the value of my angle always increases with the evolution of the time since I impose a constant torque on the crank.

How can I do to observe the Euler angles of a body (parameterized with absolute coordinates) without any limit between [-pi,pi]?

Thank you for your help.

PS: I insert my model attached

Hello everyone. I am trying to make a position time graph of a charged particle in an gravitational and electric field. This is just for an application of Maple to Lagrangian mechanics. I have set up my Lagrangian, did the Euler-Lagrange equation, and solved the differential equation. When I go to plot it, just the axes show up and I dont have a line. I have followed other examples of Lagrangian mechanics in Maple and its still not working. Here is the code for the odeplot:

Eq7:=dsolve({Eq6,initial},{q(t)},numeric,output=listprocedure)

odeplot(Eq7,t=0..10)

Eq6 is the Euler-Lagrange equation for my system, initial is the initial values, and q(t) is the position of the particle.

Any suggestions will help.

If i have to solve the eq. i have to guess what U2 is  until i get close to U1 that the error is ok. can i do this in maple. or du i have to make program.

Hi,

Recently a a simple problem which i can not handle by myself, made me confused.

I have simple code of maple which is not stable at all. Everytime I run the code, the final result which is the determinant of a matrix, changes and I can not see the problem with the code. In fact i noticed that problem occures when the matrix is being build by culculating the coefficients of some constant values.  I have attached the code. Could you see what is wrong here?

Thanks by the way.

Hi,

The default way a prompt shows on my maple is

[> blah blah blah

but i see in many worksheets including maple help pages that it shows as

> blah blah blah

My Question is how do i remove that left square bracket "[" from appearing ?

   Hi, there

 I work with maple 13 and made a file that its contet is plotting curves and its size is 

151 MB.Now when I want to open it the file cannot be opened completely only about a quarter of its contents rises.

Thanks for your help

hi, is there a way to change color of the page in Maple 18? in fact I am preparing my lectures using slideshow option and want to change the color instead of the default white.

Hi guys,

       I have the following Lagrange function. 

       (Note :w is the generalized co-cordinate.) 

       L := (diff(w(r, t), t, r))*v(r, t)

       ( I know

        If L =diff(w(t),t)*v(t)..... I can write EulerLagrange(L,t,w(t) but I dont know how to handle above function)

        Thanks in advance!!!

I am having issues opening my final year project, it was working an hour ago and now it will not open. When I try to open the file it brings up a box title TEXT FORMAT CHOICE with the options: MAPLE TEXT, PLAIN TEXT, MAPLE INPUT and CANCEL.

This is all my work and I need it to complete my year.

Any help with how I can rectify this would be extremely helpful.

Many thanks
