We have just released an update to Maple, Maple 2017.1.  It includes improvements to the display on high resolution monitors for the debugger, MapleCloud, and help system table of contents. It also contains a variety of small improvements to the math engine, including in limit, series, Physics, typesetting, and PackageTools. This update is available through Tools>Check for Updates in Maple, and is also available from our website on the Maple 2017.1 download page.

In some cases, maple is able to return a series expansion when line A is called but fails to do so when line B is called, and in the help page for asympt it defines them to be identical procedures:

A: asympt(f,z)

B:

this has generally occured when ever the function f is of the form:

where g(z) has an asymptotic expansion and when asympt(f,z) is called, maple provides this expansion divided by the exponential function, however line B as prescribed above returns an error. 

So, my question is, which line in showstat(asympt) is responsible for catching the error which line B as above encounters?

I am computing some finite points in the plane. Then I'm using point style plot to plot them. My points have order and I want to conncet the i-th point to the (i+1)-th point with a line segment. I searched the help but I didn't figure out how to do it. Is it possible to do this in Maple?

If I just want to define an itegral and do not want maple to simplify it to a closed form, what should I do?

For example, I want define

s := int(exp(-x^2)*cos(2*x*y), x = 0 .. infinity).

Maple automatically simplify s to

(1/2)*sqrt(Pi)/exp(y^2)

But I want to keep s in integral form.

This Saturday is Canada’s 150^th birthday. As you can imagine, the country has been paying a lot more attention to this year’s anniversary than our usual low key approach, and as a Canadian company, we at Maplesoft decided to join in the fun.

And what better way for Maplesoft to celebrate Canada’s birthday than to create a maple leaf in Maple! 

So here is a maple leaf inspired by the Canada 150 logo, which was created by Ariana Cuvin, a student at the University of Waterloo and former co-op here at Maplesoft:

Here’s the code to reproduce this plot (more details can be found in this follow up post):

Know other ways to plot a maple leaf in Maple?  If so, please share them below - we’d love to see them!

Is there any method or a command to use or type so Maple start running something or evaluating and if it took more than a specific amount of time, then itself automatically stops itself without needing me to interrupt the evaluation?

For example let's say I wrote a proc, for some inputs it may compute the output fast but in some it may even don't answer after hours. Now I am writing a for and I don't know for which steps it can answer in less than a minute. So I like to add something so that Maple starts the FOR but in steps that it takes more than a minute, it automatically stops evaluation at that step and jump to the next step.

I am trying to plot some graphs for a differential equations class. I need to plot two equations (soln1a, soln1b1) in one graph, with the two curves overlayed on each other. I am trying to plot them on a graph named "gr1c". The error I get says "Error, (in plots/multiple) empty plot". Clicking on the error results in a webpage saying that "There is no help page available for this error".

When I plot each equation separately, there are no errors. The graphing command that works for soln1a is 

gr1a:=plot(rhs(soln1a),dom1,color=blue);

and the graphing command that works for soln1b1 is

gr1b1:=plot(rhs(soln1b_1),dom1,color=purple);
 

My code is as follows. I would greatly appreciate any help ASAP to remove the error. Thank you!

with(plots):with(DEtools):

K:=9;
deG:=diff(theta(t),t,t) + mu*diff(theta(t),t)+K*sin(theta(t))= 0;
deL:=diff(theta(t),t,t) + mu*diff(theta(t),t)+K*theta(t)= 0;
Iv:=theta(0)=0.75, D(theta)(0)=2.0;
dom1:=t=0..10;
soln1a:=dsolve({eval(deL,mu=0),Iv});

soln1b_1:=dsolve({eval(deL,mu=1),Iv});

gr1c:=multiple(plot[soln1a,soln1b1],dom1,color=[blue,purple]);
 

Unfortunately, the Differential Geometry package is too difficult for non-mathematicians. Is there a package in the Maple for classical differential geometry?

dear all,

I have a problem when I try to find points on boundary of the surface.

the surface ploted from a matrix as follow:

please help me to generate a bondary curve of this surface.

Thanks

Dear all,

I want to plot three different plots but not at once! I mean I want to have an animated plot / gif file which shows the plots one by one:

first plot1, then plot2 is added, and at the end plot 3 is added!

Let's say my plots are

plot1:=plot(x,x=0..3)

plot2:=plot(x^2,x=0..3)

plot3:=plot(x^3,x=0..3)

Do you have any suggestions for me?

I have made a program to plot y(t) vs x(t). Can you please modify to plot y vs x data from an excel file.

Given x in A column and y in B column in 5 rows.

Example data: [[1,1],[2,4],[3,9],[4,16],[5,26]]

Thanks.

x dot produces x dot (t)   

How do I suppress the t in the output display?  The help page shows an Unsuppress all so I thought a Typsetting:-Suppress(all) would do it, but it throws an error message. 

Typesetting:-Suppress(x(t)) would do it but I'd prefer the option all.

I have a set of points. I want to make a linear spline of that points and plot the resulting function:

function:=CurveFitting[Spline](points_x,points_y,x,degree=1):

However I need the function to define constant y endpoint values where x is out of points_x range (i.e. first-derivation is zero where x is out of points_x range). Endpoint options does not work for me.

             constant1   x < xmin
function :=  ..
             constant2   otherwise

How can I define spline function like this?

I've got Maple 2017 linked to MATLAB R2017a but I can't get MATLAB R2017a linked to Maple 2017.

I've got MATLAB R2016b linked to Maple 2017.

Any ideas? (Or do I just need to wait for an update?)
