Hello All: I recently just purchased Maple, so perhaps I just don't know how to do this yet, but I think the ability to plot data on world maps would be a great feature to include. I am an Earth Scientist and often I have to port my data to something like GMT to plot fault data or seismicity on geographic locations. I know that both IDL and Matlab have those capabilities, and I think it would a great feature to include in Maple. Other solutions of this sort have just created ports to the GMT commnads. R creates a port to the GMT system calls, and SciPy with Matplotlib w/ basemap allow one to plot data on world maps.

I have maple 9.5, on win xp professional. It worked well for a long time. Once I installed i.explorer7 and I had some problems. I resolved all of them except that now maple 9.5 does not work any more (while maple classic 9.5 is still working). I tried do uninstall maple and reinstall it, but it still does not work... When I run maple, I do not have any error message, simply maple do not start. Any suggestion? thanks giovanni

The search engine for Maple 10's help pages could be greatly improved if it used fuzzy techniques. At present, unless the query is spelled correctly, the answer is No Matches Found. Perhaps Google could be persuaded to provide an engine... but without ads please! J. Tarr

Has it ever been considered to have some sort of Maple specific publication in connection with mapleprimes ? Some sort of refereed or peer reviewed publication available to the public or mapleprimes/maplesoft, that members of either of these entities can publish to. Even if it's only available online. was just wondering. v/r,

My last post that I typed in the how do I with maple forum, was cut off after I posted it. can someone take a look at this ? Tedious typing the samething more than once. I'm also having a problem again with the misalignment of the text box for replies to postings. It gets shifted far to the right of the screen. v/r,

Hello, I found an error in the following plotting. An error is with discont=true and the range <-5,5>x<-5,5> In other cases it is OK. plot(tan, -5 .. 5, -5 .. 5, discont = true); But when I plot tan as an expression no as a function it works correctly. plot(tan(x), x = -5 .. 5, -5 .. 5, discont = true); The whole document can be visited via View 551_error_tan_plot.mw on MapleNet or Download 551_error_tan_plot.mw

People on this forum have been unbelievably helpful. I am trying to write some worksheets to help flatten the learning curve for folks who are new to MAPLE. Trouble is, being not far from the newbie stage myself, I may very well be making significant mistakes about the capabilities of MAPLE and thus teaching people cumbersome and inefficient ways of doing things. With that in mind, if anyone has the time to critique the following, I would be most appreciative.

I am relatively new to Maple, I use the Plot Builders for instance for my plots. Can anyone tell me how to plot the Budget Constraint; Income = P1*X + P2*Y I want to do Comparitive Statics on this equation. Say, for instance change in slope when one of the prices changes. Please render me a solution. Thanks You, Siddharth

I just found this site over on O'Reilly Radar. It lists the numbers 0 to 9999 and describes mathematical properties for that number. Here are the first few numbers to give you an idea of what is there:

1. is the multiplicative identity.
2. is the only even prime.
3. is the number of spatial dimensions we live in.
4. is the smallest number of colors sufficient to color al planar maps.
5. 5 is the number of Platonic solids.
6. is the smallest perfect number.
7. is the smallest number of faces of a regular polygon that is not constructible by straightedge and compass.
8. is the largest cube in the Fibonacci sequence.
9. is the maximum number of cubes that are needed to sum to any positive integer.

Maple 11 is now available for purchase from the Maplesoft webstore. If you previously purchased an upgrade to Maple 11, you will be receiving it shortly.

If you wish to learn more about Maple 11, please read the official announcement, my take on the new features, or, the Maplesoft.com Maple page.

In MapleTA (2.51) we are using an algorithm to generate the components of a formula. The components are then combined and the MathML function called to render the formula. We have discovered a problem that occurs when a negative number follows an operator, i.e., 5a+4b+-7c. Here is a simplified example of the question code: mode=Multiple Choice@ editing=useHTML@ algorithm=$a=rand(-5,5); $b=rand(-7,7);@ question=a is $a
b is $b

sin(v^$a)+$b

${maple("MathML[ExportPresentation](sin(v^$a)+$b)")}@ answer=1@ choice.1=z@ If $a, $b, or both are negative, the following error is generated:

The Cartesian product of a sequence of m lists L₁, ..., L_n, with list i having n_i elements, is given by the sequence of Π_i n_i lists [L₁₁,...,L_m1], ..., [L_1n1,...,L_mnm], where L_jk is the k-th element of the j-th list.

Dear Sir: I try to solve a set of simultaneous equations. But, it is not easy to get a solution by using MAPLE package. restart; eq1:=P-2*P*cos(w*t[2])+(P+1)*cos(w*t[3])=0; eq2:=-2*P*sin(w*t[2])+(P+1)*sin(w*t[3])=0; _EnvAllSolutions:=true: _EnvExplicit:=true: solve({eq1,eq2},{t[2],t[3]}); But, MAPLE does not give me what I want. I expect that the solution should be in the following way: t[2]=(1/w)*arccos((4*P^2-2*P-1)/(4*P^2)); t[3]=(1/w)*arccos((2*P^2-2*P-1)/(2*P^2+2*P)); where w and P are positive constants. Could you help me to get the solution? Thanks

This example shows that restart command does not work correctly - it means that it does not clear stack memory(internal memory). The following example shows it. In that procedure there are some mistakes, but I think that the restart command should work correctly whith them. If you execute the following procedure three times (maybe twice, it depends on the computer memory capacity, but I do not amount to more than three times), the Maple system falls down with out of memory (execution stop - the stack ) - why? You call the restart command, so where the fatal error is. It does not depend on the correct usage of statements in the procedure.

Dear Sir: Following is the inverse laplace of the given equation. restart; with(inttrans): X:=-k*(m[1]+m[2])/(s*(k*(m[1]+m[2])+m[1]*s^2*m[2])); invlaplace(X,s,t); The result is something like "1-cosh(a t)". I expect that the result is similar to "1-cos(a t)". How could I get what I want to get? Thanks in advance
