I am missing the F1-help to work properly after highlighting words
at least for the following

invfourier ---> completely missing (it is in inttrans)
invlaplace ---> completely missing
invmellin  ---> completely missing
fourier    ---> MTM[fourier], but not inttrans

Parts      ---> completely missing (expect it in IntegrationTools)
Flip       ---> ImageTools[Flip], but not to IntegrationTools
Change     ---> selection, but no IntegrationTools

I recently discovered a minor variation on the technique of building a set using a table. The purpose for using a table rather than inserting new items directly into a set is that, in a loop, the latter technique is O(n²) rather than O(n).  The way I would normally do this is to assign a counter and an empty table, and then, in a loop, compute the new element, increment the counter, and insert the element into the table at the counter index.  For example,

It's not often that a funny music video is made about Fractals. Here is something very special:

Ever wondered how you can create filenames by cycle.

Well, I did, because I needed it. And I came up with something that works and because once i forgot it, I decided this time to put it here. At least, I won't forget again :) If you have a better way to do it, please, say so.

The idea:

>A:=`/home/Data/file_`; B:=`.txt`;

>for i from 1 to 3 do C:=cat(A,i,B); writedata(`C`,[i],integer);od;

solve used to be one of Maple's strongest commands -- it even subsumed simplify in power.  But, over the years, dsolve slowly took over as the most powerful comand.  At the same time, people started realizing that within the framework of differential equations, the toolbox was actually larger than the one for algebraic equations (and most algebraic tools are still available).  So many tasks that one thinks of doing purely algebraically can also be done using differential equations, with perhaps the most surprising one is to factor multivariate polynomials via partial differential equations.

For t := x^(1-I), f := arcsin(t) + arcsin(1/t) i have problems with

  dd:= PDEtools[dpolyform](y(z)=f,no_Fn);

                    dd := [-- y(x) = 0] &where []

Hard to believe it's that time already...we are pleased to announce that the winner of the monthly Maple Mentors Award for June is Mario Lemelin (aka lemelin) .  Mario will receive a prize of his choice to thank him for his involvement with the MaplePrimes community.

Congratulations...and keep on posting!

We are happy to announce the latest product to the Maple line of software.  MapleSim is a high-performance multi-domain modeling and simulation tool which will revolutionize how you bring products to market.

I want to put in the plus or minus symbol (+/- in ASCII) into a text region (standard math), as in the quadratic formula.  I am using the classic interface in version 9.5.  Can this be done?

We are going to show a roundabout but rather effective method of solving some rather complicated (definite) integrals in closed-form via a rather unusual method: a special factorization of linear ODEs.  The example we will use is a 2 week old question that has yet to get an answer.

First, the problem: compute the integral
