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?

See http://mathematica.stackexchange.com/ and compare with MaplePrimes.

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

Originally y, renamed y~:

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?

Interesting behavior!!

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:                                                    ...

I have problems with the time delay the procedure for computing the Hough transform of the image that Annex. Delay 5534.875 seconds. How to improve, optimize the procedure, to be more efficient at runtime?

Hi,

I have a system consisting of a multi-body system and various modelica/maple custom components. The problem is whenever I re-run the simulation even though all the simulation settings are same, the simulation results are inconsistent. There should be no difference between each simulation as all the parameters/settings are same. I am attaching two pictures which are both obtained from two successive simulations
