Recently, a Maplesoft customer service representative received an e-mail from one of our users with the subject line: A Simple Thank You. We wanted to share this message with you, as it demonstrates how the power and flexibility of Maple helped one student get ahead in his studies.

The following is an actual email we received from Eli E., which describes his experience using Maple as a university student.

Hello, my name is Eli...

Some time ago, I posted a two-letter-words quiz for Scrabble players. That one is particularly useful to beginner players wanting to increase their scoring opportunities. I've created another worksheet for those looking for a greater challenge. This one tests your knowledge of the three-letter words that can be created from the valid two-letter words. Enjoy!

In it's recent edition of Mathematics Today (in print and online), the UK-based Institute of Mathematics and it's Applications, compared 4 symbolic solvers: Maple 15, Mathcad 15, the student edition of Matlab v5 and the Casio CFX-9970G calculator, concluding that "Maple would be the natural choice for research mathematicians, theortetical physicists, those working in any area where mathematics is demanding or for mathematics undergraduates for whom costs are lower"

Revision Note:
I have updated the graph in the attached Maple document based on Doug Meade's comment below.

There are two interesting threads about definite integration on the usenet group comp.soft-sys.math.maple posted in the past few days.

The first thread is more about the wrong result coming out of Maple's int command when computing via its `MeijerG` method. Motivating examples there include

int(cos(t)/(1+t^k), t=-infinity..infinity);      # for k=10,12,14,...

The poster demonstrates using residues to obtain a terse result.

In the second thread the poster examines the ideas that the solutions involving RootOfs (as returned by the `ftoc` method) may suffer from numerical difficulties during floating-point evaluation and are unnecessarily complicated when re-expressed in terms of more standard functions (ie. allvalues, then simplification...).

For those interested, an existing `contour` method exists within `int`. It is not very strong however. One can examine its source using commands such as,

showstat(`int/definite/contour`);

showstat(`int/definite/contour/def1`);

etc.

See also Methods of contour integration on wikipedia.

My answer in this topic does not load for some reason, so I had to create this post.

Following on from the 3D plots of the Earth globes in comments to an earlier post, here's some hacky code to grab longtitude and latitude.

(nb. This code attempts to send the IP address of your primary DNS to www.geobytes.com so don't run it if you don't want that action.)

if kernelopts(platform)="windows" then
   res:=ssystem("ipconfig /all"): res:=res[2];
   StringTools:-Search("Primary Dns Suffix",res);
   ans:=StringTools:-Split(res[%+36..%+70])[1];
else
   ans:=ssystem("hostname -y"...

Recently, I published the following paper.

"Calibration of a radiocarbon age", Nonlinear Processes in Geophysics, 19: 345–350 (2012).

The paper explains that all radiocarbon dates are inaccurate, due to an error in the handling of the statistics.

The paper has a Supplement, which includes a program to do the statistics correctly:

We have been using MapleTA for many years (since version 1.5) and have version 8 hosted on a Maplesoft server. Recently, we looked into buying the Blackboard connector. It is disappointing that we have not been able to go through with this because of an inadequacy in the connector. As I understand it from our technicians, in Blackboard a course is identified by four attributes ID, year, calendar and title. These account for different presentations of the same course in different...

Eleven new Clickable-Calculus examples have been added to the Teaching Concepts with Maple section of the Maplesoft website. That means some 74 of the 154 solved problems in my data-base of syntax-free calculations are now available. Once again, these examples and associated videos illustrate point-and-click computations in support of the pedagogic message of resequencing skills and concepts.

This message has been articulated in ...

This post is a further exploration of the optimization problem of finding a point on f(x) = sinh(x) - xe^-3x closest to the point (1,7).  The problem is part of our Teaching Concepts with Maple web site, a collection of video examples and Maple worksheets designed to illustrate how Maple can be used to generate...

I guess there is a limit bug here somewhere.  With MultiSeries things are OK...

L:=(x*BesselI(k-1, x)+x*BesselI(k+1, x))*BesselI(-k, x);
L := (x BesselI(k - 1, x) + x BesselI(k + 1, x)) BesselI(-k, x)
simplify(limit(L,x=0)) assuming k>0;
                               0
with(MultiSeries):
simplify(limit(L,x=0)) assuming k>0;
                          2 sin(Pi k)
                          -----------

This is a comment and warning to anyone in the United States using MapleTA 8. 

If you get login information using LDAP, MapleTA 8 gets the "employee number" from the LDAP data base  and displays it on the screen when a person is logged in.  After talking to our IT people, they acknowledge that this is a FERPA violation when using MapleTA in a lab where people can see screens of other people's computers.

Our IT people have contacted Maplesoft for...

I wanted to point the MaplePrimes community in the direction of the new MapleSim training videos. These videos cover a variety of common tasks within MapleSim, and demonstrate the concept in just a few minutes each. I'd highly recommend you take a look at them to learn more about using MapleSim.

They're located here: http://www.maplesoft.com/support/training/videos.aspx
