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.

To see Maple 11 in action you may also be interested in viewing the professional and academic demo videos.

 

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

We have an opening for a software developer in the Mathematical Software Development group at Maplesoft. This opportunity involves joining a team of highly educated and motivated people who are developing and implementing sophisticated algorithms for mathematics at all levels, from undergraduate education through to professional research. The successful candidate will have a strong background in both mathematics and computer science, preferably with an advanced degree. Experience with Maple, particularly with programming in Maple, is a definite asset.

I did not see an official policy about asking homework questions on MaplePrimes (at least a search for 'homework' did not turn up anything relevant). A number of other sites and mailing lists which I am on have such policies. A particularly like the policy from the Haskell-cafe list. It strikes an excellent middle-ground between being helpful and active participation in academic dishonesty.

I have a question about Maple 10 updates. If I would like to update my Maple 10.00 installation which of the updates should I install to get completly Maple 10.06. Thank you. Vladimir

Over the last couple of months I have been writing various procedures related to quantum optics and quantum mechanics in Maple 10. I have decided to put all the procedures together in a MODULE that can now be found online here: Toolbox for Quantum Optics I have also included a manual (in pdf format), an example worksheet and the module.
