Hi,
I had written some help pages in Maple 18 that I just migrate in Maple 2018.
This seems correct except one single point: when I try ot access them from the help menu, their names are preceeded by a  "WS" label and, when I click on it, the help page appears in a new window of my Maple's session, not in the help window.
I guess "WS" means "WorkSheet" ?
How can I force the halp page of "my" function to appear in the main help page window?

(hope I was clear enough)

Thanks in advance
 

The example in Maple:

Download Example_to_Mapleprimes.mw

The help page for interface states that errorbreak can be between 0 and 2, however despite being able to do so according to the output of 
<code>

interface(errorbreak=0)

</code>

My worksheet still breaks on most errors.

Is this something I am doing wrong, or is this because i am using maple 2016?

How to find PARETO FRONT WITH fminsearch Command for weighted sum method In Matlab R2015a

I am having problems with the attached worksheet, in which I am attempting to solve a couple pair of PDEs, particularly in defining initial and boundary conditions.  See MapleExample1c.mw

Can anyone help?

Hey guys, I'm a new Maple user and I've been struggling to figure the collect command out.

I made a smaller example to show what I am looking for

I want to find out a way to use collect command and go from "c" output to "d", choosing the terms I want to be collected as common factors.

I'm also uploading the files if it's of any help, The one called question is the example in the picture above and final objeticve is the big expression that I`m trying to factor.

In the final objective file I'm looking for a way to make the "i" output be factored like this as:

Wi δ Wi (...) + Wi δ Wf (...) + Wi δ θi (...) + Wi δ θf (...) + Wf δ Wf (...) + Wf δ Wi (...) + Wf δ θi (...) + Wf δ θf (...) + ...

Thanks in advance

My problem is as following:
Our school has a requirement that we have to show the numeric values, when we calculate. And i was wondering if there's an easy way to do it?

Example of how i would normally do it:
A:=5
B:=5

C:=A+B = 10. 

What they want:
A:=5
B:=5

C:=A+B = 5+5=10

Does anyone have an easy way of doing this? Because in an exam I wont have the time to plug in the values myself.

Hi,

I try solve this differential equation:

de := diff(y(t), t)+2 = (y(t)^2+1)*(diff(x(t), t))
dsolve(ode);

Maple not solve.

Any help?

Regards

Hello, I try this integral, but Maple not solutions, the answer is the same integral.

int(N*exp((2*(-(1/2)*x^2-2*a^2*ln(x)*x/(-2*x^2+2)))/sigma^2)/(-2*x^2+2), x = -1 .. 1)

N,a, sigma are constants.

What is the procedure to migrate a Maple license on a new PC ?

Hey, I have been using maple for a whole 30 minutes, and have no idea what I am doing! I have some code set up to run the Eulers approximation to solve an ODE.

The code seems to run fine, but in the final output where it should give a number value, I am getting 6+0.10f (where f is a variable define beforehand). My friend who has run the same code does not run into this problem.

The Maple software is a on a public school computer, so maybe the specific one I am using has some setting set up that are not default?

Does anyone know what is going on? In the end I would like the output to be a decimal number.

Dear all,

I have two vectors, I would like if possible using maple  I find  determine the real number t  such that  the subset  { v1, v2} of C^2 ( where C is the set of complex number) is  linearly dependent?

Hi, I have the following simple differential equation. 

2x dx -9y^2 dy = 0

How can I enter the command to solve it? I know I'm supposed to use dsolve command, but I keep getting an input error saying that it expected an ODE. Google says that said message is because for whatever reason Maple cannot understand dx or dy, and that instead I need to use diff command. But when I enter: 

2x diff(x) - 9 y^2 diff(y) = 0

I get another error. I have tried other combinations, but at times I get errors like y(x) and y cannot both appear in the given ODE, which I don't understand why they can't as they are like basic run of the mill ODEs, so I'm a bit confused. 

I have also checked Maple's docs but they don't help either, I tried the first example given here: 
https://www.maplesoft.com/support/help/Maple/view.aspx?path=dsolve
 and I got the same "expecting an ODE or a set or list of ODEs" as in my own examples, so I'm guessing the docs are assuming steps or some configuration. 

How am I supposed to enter the command? Thanks in advance!
