Hello, I sent this letter to MAPLE tech support and they suggested that i post it here. After using MATHCAD for a number of years, I recently purchased MAPLE 10. I am really blown away by this software’s depth and versatility. I am particularly impressed by how well geared it is to do symbolic math, and by the fact that with MAPLE you can see the steps involved in a complicated symbolic integration. I do find however, that the price of MAPLE’s extra power is that it is less intuitive and has a steeper learning curve in comparison to MATHCAD. There is definitely one area in which I have found MATHCAD is superior to MAPLE. I realize that I may not be fair to MAPLE. There exists the possibility that one can do in MAPLE a certain thing I have been doing in MATHCAD and I just don’t know how to do it yet. It is that possibility which is behind this letter.

Can anyone give me some guidance on how to approach a singular integral similar to this: f:=Int((y^2-1)^(1/2)/y/(1-1.5*y^2+(y^2-1)^(1/2)*(3*y^2-1)^(1/2))*(1-1.5*y^2)*(.1e-5-(.1066590211e-4*y+.1e-2*(y^2-1)^(1/2))^2),y = 1 .. 1.4037); It arises from a solution of the Wave equation from an impact to the elastic half-space. I am working through a paper by G. Eason (J. Inst. Maths Applics)from 1966 where integrals of this type are evaluated numerically, but the details are left out. Thanks, Ken kagd@lehigh.edu

Hello! I got a trouble to get the answer of following exponential function with summation. I expect that the answer should be "Heaviside" forms. However, the maple software does not go further. restart; assume(i::posint,n::posint,s::complex); eq1:=sum((-1)^i*exp(-s*T[i])/s,i = 1..n); inttrans[invlaplace](eq1,s,t) assuming T[i]>0,T[i+1]>T[i]; I am a novice for maple. Is there any procedure routine? Please tell me about it. Thanks. Y-G Sung sungyg@chosun.ac.kr

You can now use Google code search to look only at source files. Right now, Mathematica is handled natively (as the drop down on the advanced page shows), but one can still get to maple files by specifying file:\.mpl as a work around. While it can also be used to search plain text files (to search mws files) as well as XML (i.e. mw files), it is less clear how effective searching in those types of documents would be. People seem to have taken to posting to the Google Code Search Group to ask for their favourite missing language.

Hello i wonder whether its possible to solve elliptic pdes numerically in Maple10. I didnt succeed. I have a 2dim. poisson equation with the source term being the output from an other pde, i.e the source term can not be given in closed form so how to integrate this? i always get the message that Maple10 can not solve elliptic pdes Thanks for any ideas

Hello, I have 32 pc installed with ghost. The OS is SuSE 10.1. I try to install Maple 10 but at the end of the installation of Maple I have the message "Unable to determine the host ID of your system" When I install Suse 10.1 fron the DVD, not from ghost, I can install Maple 10 without problem. I tried to fix the host ID with the command hostid but the Maple says "Unable to determine the host ID of your system" Some help is welcome

Hi all, Is there a Maple .INI file that I can edit so that I do not have to continually enter packages or change fonts for styles that I wish to use instead of the default values. For example: with(package) with(package) Set Maple to be initiated with any package without repetition? TIA Larry Ciak aka malt_master@comcast.net

I have programmed a procedure to calculate certain polynomials associated to matrices. There is a variable for each column of the matrix, say z1,...,zn, and the polynomials get quite large as the matrices grow in size. The procedure gives the correct answer but, for large matrices, the terms in the resulting polynomial are not collected properly. For instance, terms z1*z2*z3*z4 and -z1*z2*z3*z4 might both appear. "Simplify %;" does not cancel these terms. By copying the answer and pasting it as a command, I can cancel the terms but most answers are so big that copying cannot be done in practice (hundreds of pages).

I try to solve a large class of origami folds using Maple, this is the mw file (at this stage, only one step missing, I'm not very good with trigonometry using Maple).

At this end I only have to express the angle alpha in function if the anlgle theta and the lengths y_a and y_b.

More explainations soon.

The question of how to scale the x-axis with intervals of Pi has been raised on a number of occasions. Inspired by a contribution from Will, I produced the procedure and examples shown in the worksheet attached below. Hopefully, Maple users will find it useful. J.

Does anybody know why Maple's support of PDF is so poor? I posted a forum topic entitled "PDF support" in the past but didn't get any satisfactory answers. Suppose that I want to automatically generate a bunch of PDF files in Maple and manually saving each one as PDF isn't an option because it is too time consuming? Am I the only Maple user who has ever encountered this option? A search of the web seems to indicate that this is the case. I want to use Maple over Mathematica, but this is one issue that has prevented me from making the switch (permanently) so far. I am currently running Maple 10.04 for Mac on OS 10.4.8 on a G4.

Hi all, I am Using Maple 10. i am getting a frequent bug When i plot a 3d graph. Description: In a 3d plot, if i rightclick after rotating the graph, maple exits automatically. can somebody please tell me what's the problem? Thank you Divahar.J Indian Institute of Science, Bangalore, India.

Hi Community! I am using maple in excel and... I have a question When I introduce this expresion =Maple("array([[1,2,3],[4,5,6],[7,8,9]]);",A18:C20) The output is: matrix([[1,2,3],[4,5,6],[7,8,9]]) on cell A18. Why? The output don't share on each cell this array. On the cell A18 would be the first element of the matrix, 1 On the cell A19 would be the second element of the matrix, 2 ...until the cell C20 it element would be 9. Which could it be the solution? I hope, you understand me Thanks!
