I cannot make Maple find the solution for the integral of sqrt(x/(1+b*x^3)) assuming x>0 and b>0, which is 2*arcsinh(sqrt(b*x^3))/(3*sqrt(b)). Mathematica does this without any problems. What am I doing wrong?

How do I stop maple from running the rest of the worksheet in case an error occurs in the middle of it? Which command should I use?

More specifically, I have a program in which I input the masses of the particles and then the program will calculate the corresponding parameters of the potential, and will do a lot of other stuff with these parameters. However, it these parameters happen to be complex, the program should simply halt with a warning: "your parameters are complex, cannot continue".

Good day! Some of my tasks are quite time consuming. What maple command I have to use in order to get some sound signal when calculation is over?

I am trying to set up a procedure for creating a matrix of user specified size.  Basically, I want the user to be able to specify the size and the values of the internal parameters and maple will generate the matrix.  The matrix has the form:

[e   h1   0   0   ...    0]

[h1  e    h   0   ...    0]

[0    h    e   h   ...    0]

...

I have a module which is an argument to a procedure.

When I "trace" this procedure, the entire module is  printed (as it should).

Is there a way to NOT print the contents of the passed module? It is annoying when debugging.

Hi

I've got a list of inequalities

[x > 5, 10 < x]

and I need to plot the region by

plots[inequal]( [x > 5, 10 < x], x = 4 .. 11, y = 0 .. 1);

but I don't want to specify x-range.

So how can I get the numbers from inequalities and generate something like "x = 5-1 .. 10+1"?

Thx :)

I realize that Maple itself does everything but I would like a simpler cheaper solution for a number of computers in my classroom.  Multiple licenses of Maple is not an option.

Hi all,

I am stuck again in a simple problem of creating a M*1 Matrix.  I have attached a Maple file for your kind consideration.

I shall be looking forward to your reply.

Best Regards

Hi,

> assume(y::prime)

Originally y, renamed y~:
  is assumed to be: prime

I don't understand this answer:

> is(>0)

      FAIL

Just to clarify, so if an issue is brought up here in mapleprimes there is a possibility that it will go un-noticed by maplesoft?

I realize some issues brought up by people are sometimes solved within, but there is an occassional request for input from maplesoft on these forums that go un-answered.  Just recently a question only maplesoft could answer here and there has been no reply http://www.mapleprimes.com/posts/123111-Maple-1501

I am going to guess...

I want to solve a set of ODE equations numerically,there is 5 equations with certain boundary conditions,please help me,what kind of dsolve order could i use? when i use dsolve({sys,bcs}type=numeric) i get an error that say me:system must be entered as a set of equations! how can i solve it?

Hello everyone

I'm trying to do a fit for some points using a model function. However, I don't want to use the full range of the independent variable in the model function because I know there will be no fit then. How to assign a range for the fitting variable?

In the case my writing is not clear, here is what I mean:

xdata:=points

ydata:=points

modelfunction:=f(x,parameters)

Fit(f(x,parameters),xdata,ydata,x,rangeofx=r);

Interesting behavior!!

Hi, i wrote my script file some time ago, and found that I wrote `:=` in one of the equations. when I remove the ``, just let it be :=, it does not work and is spending a long time to evaluate. May I know what does `:=` means please?

Thanks.

Hi everyone, 

In my research project, I needed to evaluate a multi-variable integration. I'm trying to do this in Maple, and seems no matter I use Int or int, it failed to evaluate the integration. 

Here's my code:

I'm integrating a joint probability density function which is basically a multiplication of four PDFs of four Gaussian distributions:

> mu := 0:                                                    ...
