Hope somebody can help me! I installed Maple on my computer, but everything is very small , for example the bar in the top with all the small icons. It is the same thing when I make plots. The values on the axes are very small. How can I change this?

I have taken a photo of the problem, don't know if it helps.

The Maple 2015.2 update is now available for Windows and Linux users. It provides official support for Windows 10, connectivity to the latest MATLAB release, support for MapleSim 2015.2, updates to Physics, and a variety of small improvements throughout the product.  It is available through the Check for Updates system, and is also available from our website on the Maple 2015.2 download page.

The Mac update will be released as soon as we have finished fixing the problems on Mac OS X 10.11. We’re working on it.


We are looking for enthusiastic Maple users to become Maple Ambassadors, to inspire and educate others about the benefits that Maple brings to education.


As an Ambassador, you will have the opportunity to influence the development of Maple through regular meetings with Maplesoft developers, get advance news of upcoming features and products, get assistance with Maple events on your campus, and more. In return, we ask that you do what you are probably already doing – sharing your experiences with Maple, answer questions on forums (like this one!), sharing your Maple applications, providing us with feedback, etc.


You can find more information and an application form at Maple Ambassador Program. We’re looking forward to hearing from you!

     I have a list of 603 integrals that I want to evaluate. Unfortunately, I can't get Maple to do most of them. Mathematica can do some that Maple can't, and returns an answer in terms of BesselJ functions. So my question is 2-fold

1) Is there a way to make Maple do this integral?
2) If not, is there a way to efficiently convert 603 expessions to Mathematica and back?


assume(k1::real, k2::real, R::real, R>0);
a :=cos(x)*exp(I*(k1*R*sin(x)+k2*R*sin(x)-4*x))*sin(x):
int(a, x=-Pi/2..Pi/2) assuming real;



assume(k1::real, k2::real, R::real, R>0);

a :=cos(x)*exp(I*(k1*R*sin(x)+k2*R*sin(x)-4*x))*sin(x)



int(a, x=-Pi/2..Pi/2) assuming real;

int(cos(x)*exp(I*(k1*R*sin(x)+k2*R*sin(x)-4*x))*sin(x), x = -(1/2)*Pi .. (1/2)*Pi)


Mathematica Answer

Hello, forgive me if I used bad english, I am not a native speaker.


Anyhow: I have to decide the set of coordinates looking at the grafs intersections.  (I hope you understand that)


This is my function: f(x)=1/4*x3-x2-x+4


When you plot the function you see that the intersections is (-2,0) (2,0) and (4,0)


BUT I have to use a command to find these three intersections, plzz help me!


THANK YOU indeed.



[point of] intersection

Hi everyone,


I'm trying to solve the following eqauation but Maple gives me the answer (( RootOf(mexp(-_Z*(m-1))*d^2-theta+_Z*theta-theta*c*t__kj) ))


The equation is:

solve(mexp(-(m-1)*t__ij)*d^2-theta+theta*t__ij-theta*(sum(t__kj, k = 1 .. c))-m*eta*(diff((1-1/exp(t))^m, t)) = 0, t__ij);


Could you please help me??


What is the meaning rootOF? Is there any explicit solution to that equation??


Thank you for your help

For those who are running Maple and/or MapleSim on the Mac, and who may have missed an earlier question on this site, we wanted to let you know that there are some problems with running Maple and MapleSim on the new Mac OS, Mac OS X 10.11 (El Capitan). We’re working on a solution, which we expect will be ready in a few weeks. We’ll keep you posted, but in the meantime, please delay updating your Mac OS for now to avoid problems.



I want to solve these two differential equations. I have the initial conditions:
What am I doing wrong?


I would like to know : how I can get all the contents of the module GetMultibody of MapleSim?

Is there in classic maple a function enabling me to ask the content of a module ?

Thank a lot for your help.


Can Maple compare irrational numbers?

A simple command like   if(2<√5,0,1)   is not working for me. 

The function hypergeom([2/3,2/3,2/3],[-1/3,4/3],z) has radius of convergence 1 and real coefficients.

But Maple tells me evalf(hypergeom([2/3, 2/3, 2/3], [-1/3, 4/3], 99/100),50);

is -138.999 + 0.0012 I

It should be more like −138.9962313171333091754979138344422738025

I want to work (cross products, differentiating and simplificating) of three dimensional vector functions.

But I'd like to work with them as vector, not as components. Is it available in Maple?

The GroupTheory package in Maple includes facilities for working with finitely presented groups - groups defined by finitely many generators and defining relations.  We now have a video tutorial that covers the basics of this aspect of the package.  As always, we appreciate feedback and suggestions regarding this feature, or new features that you would like to see in the GroupTheory package.


i am trying to put u[0](zeta):=0 in maple but it gives an error, however it accepts u[0]:=0 but i have to involve zeta in it. help please.

 here is my program 

bc1 := u(x, y)-0;
dydxf := (1/2)*(-u[m+2](zeta)-3*u[m](zeta)+4*u[m+1](zeta))/h; 
bc1 := subs(diff(u(x, y), x) = subs(m = 0, dydxf), u(x, y) = u[0](zeta), x = 0, bc1);
eq[0] := bc1;

on pressing enter a new window opens of title

clerify expression.

parts of expressions are ambigous. please select one of the suggested meanings.

function defination or remember table assignment.

then it gives the error below
Error, unable to parse


Maple 2015 has a new command, dataplot, for plotting datasets. It was designed to be easy to use and it offers several new features that are not available in Maple's other plotting commands. A few months ago, I recorded a video that gives an overview of the command. If you have any questions or comments about dataplot, feel free to post here. I'm also including the worksheet that is shown in the video:
