assume system of polynomials are above, how to test whether inverse exist

and find inverse of them

This Maple 13 so maybe things have been fixed. Here are four points whose convex hull consists of three points. Sometimes the result comes out correct, more often it does not. With numbers this small it shouldn't be an issue of roundoff. But changing digits changes the result!

Hi all

kx,ky is the wavenumber, how can I get the 4 cases of piecewise function according to kx=0,kx≠0 and ky=0,ky≠0. Thanks

J := `assuming`([4*(int(int(JJ*exp(-I*(kx*x+ky*y))*sin(2*l*pi*x/a)*sin(2*k*pi*y/b), x = 0 .. a, AllSolutions), y = 0 .. b, AllSolutions))/(a*b)], [k::posint, l::posint, a > 0, b > 0, JJ > 0])

Let a planar polygon P without selfintersections be given through the plottools:-polygon command. How to find its triangulation as a set of triangles (The indication of common sides is desired too.) in an optimal way with Maple? This is used in the finite element method.

Hi all,

I am stuck with the following problem:

convert(cos(alpha), exp); works fine for me.

Once I have the trigonometric functions in a matrix, it does not work any more:

In the latter line, A keeps the trigonometric functions. Why is this the case? Is there any way to force maple to keep the complex exponentials instead of trigonometric functions?

I am using LinearAlgebra and VectorCalculus.

I have a Maple worksheet with some graphs of 10^5 data points. When I export the worksheet to a pdf for

inclusion in a LaTeX document (with pdfpages package, this recognizes page breaks), the file is around 100 Mb, much larger than I would like.

It seems that the file is large as a figure in the pdf is not just an image, the pdf seems to contain all of the information necessary to

plot each data point individually.

Is there some way to encourage Maple to treat figures as bitmaps (or something similarly much smaller than the original figures)

upon exporting a worksheet to a pdf? I'll be happy for any suggestions.

Ok guys, so i have a bunch of datapoints in 3d (x,y,z)

I'm trying to calculate an equation using maple that will express z as a function of x and y.

I've been browesing around for like 2 hours now with no hope. Help?

Der Group,

after updating to OS X Yosemite the License data of Maple 18 are invalid. What can I do?

Hi Maple friends.

If I have y=-x^2+9 and y=x+3, how can I find the area that is bounded by the functions?

Easy enough to calculate by hand, but I need to use Maple to check my answers. Most preferably I'd like to use the Maple context menu to get the result, but any solution will be appreciated.

Thanks in advance.

Can anyone tell me where I can find tutorial explaining how to solve laplace transform? I need a tutorial that explains starting with simple resolution to advanced resolution.

Hi all;

I have following program for plotting numerous function using hybrid functions.

if g1(t) is arbitrary function and g2(t) is its approximate by hybrid functions, I want to have a table of g1(t)-g2(t) for different value of t. but the result is without numeric values. what part is wrong????

best wishes

How to calculate the Amplitude of two combined sinusoidal of different frequency and phase of a general equation as:

I need to know if the Software Maple solve, step-by-step series of Fourier and Laplace transforms? The Maple command has to solve step by step series of Fourier and Laplace transforms? or commands show only the direct solution?

Hi again,

I am lost... again. I worked with the Physics package and have obtained my result in form of a lengthy equation of commutators of non-commuting objects. So basically my problem is solved, except that I now want to compute some examples to see, if everything is correct. For that purpose I want to replace now the non-commuting objects with explicit matrices, compute the result and see if it agrees with numerical studies. However, I have no clue which command to use, because if I try it with subs, then the multiplication is of the wrong type and Maple won't multiply my matrices. I tried to use eval but wasn't successful.

Here is an exampe to see what I mean.

Thank you for your time

NOh

The following MWE shows what I mean:

with(Physics):Setup(mathematical=true):

Setup(noncommutativeprefix={MX,MY,MZ});

test:=proc()

local eq;

eq:=-Commutator(MX,MY)-Commutator(MZ,MY);

eq:=simplify(subs(MX=-MZ,eq));

return eq;

end proc:

test(); # yields -[-MZ,MY] - [MZ,MY]

% # yields 0

Any ideas how I can solve this? I would like to return the simplified version.
