Maple IDE team is launching a Tester Program that will allow us to incorporate more input in the product design and development process.

We are looking for regular testers for Maple IDE. Your testing complements our in-team testing of new software versions. By enlisting a diverse group of beta testers, we can see how the software performs when it's being used for normal, ordinary tasks. This lets us provide a more стабле Maple IDE with better user experience. As a member...

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"

### Testing for a complex number

I need to test a list of numbers to find if any of them are complex. if a complex is found then remove that complete row from the list. the potential complex numbers in my list are a, b and c. b is complex i.e has a non zero imaginery part in row 1 so only row 1 should get deleted. the a b and c were originally generated from the arcsin function. Would appreciate help on this. I know it should be simple enough to do. Thanks in advance.

Can't find what the matter in recursive occurance of this problem. Anyone knows how to sort it out, thanks

### The Spearman test

This is one of rank tests.
Non-parametric methods are widely used for studying populations that take on a ranked order (such as movie reviews receiving one to four stars).
The use of non-parametric methods may be necessary when data have a ranking but no clear numerical interpretation, such as when assessing preferences.
In terms of levels of measurement, non-parametric methods result in "ordinal" data.
After the introduction to the topic let's turn to an example.

How do I test a variable against itself to see if it has a value or not?

As an example

p1:=sin(x)
p2:=46

[seq(if(p||i=p||i,p||i,NULL),i=1..5)]  # when p||i actually equals p||i and not some value ie sequence should not include p3,p4 and p5

The Kolmogorov-Smirnov test is a widespread, simple, and effective test to check the hypotheses of the form H[0]:=F[ksi](x)=F(x), where a function F[ksi](x) is the CDF of a population distribution, a function F(x) is a given continuous function (the Kolmogorov  test), and the hypotheses of the form  H[0]:=F[1](x)=F[2](x), where F[j](x), j=1,2, are the CDF of two population distributions, both are assumed to be continuous (the Smirnov test).  See the ...

### Is there a "MapleUnit" for Unit-Tests?

Hi there,

I'm doing a lot of computations with Maple right now (currently the ancient 10 and 12 versions but maybe soon 14).

I would like to do Unit-Tests of my Software as known for instance in JUnit with Java. Is it possible or do I have to use the ASSERT(...) - statements?

### Differential Equations help pt.2

Hi! so im working on the next problems now:

Show that dV/dt = -k * V^(2/3) given that k = 0.4836 and t is measured in minutes if the original volume of the capsule is 300 ml, how long will it take the capsule to lose half its volume?

Im doing this on maple right now and see you if guys can spot my problem or my syntax:

1. eq1 := diff(y(t), t) = -k*y(t)^(2/3)

2. dsolve(eq1, y(t)) which gives me an equation

3. dsolve({eq1, y(0...

Hello, MaplePrimes!

I want to create a custom component to model dynamics of a movable pulley, which can rotate and move along some direction (translational motion). I’ve got dynamic system, which describes both motions of a pulley. Some information about this dynamic system:

Hi, all,

Is there a command to test whether two polynomials are equal to each other?

Or I have to write a procedure to do that?

Thanks.
