It is not every day that a venerable and wide-ranging standard such as IEEE-754 gets an update!  IEEE 754 dates from 1985 (that was the year it was approved, the actual work started years before).  Wikipedia has a nice summary of the changes.

Of course now inquiring minds want to know: will Maple 13 by IEEE-754-2008 compliant? [For all I know, it might already be most of the way there, with only minor tweaks necessary].

Hi

I have just purchased the download version to install on my HP dv900 laptop.  I have 2Gb RAM and over 137Gb of hard drive space available.  My account has full administrator privileges, but when I try and install the software I get a InstallAnywhere error telling em to choose another location to extract the installer file.

I have tried everything I know to try and install the software, but to no avail.  I need this software for my Multivariate Calculus class, co any assistance will be gratefully received.

Regards,

Large or involved projects may involve Maple modules which rely upon each other. Routines in one module may call routines in another module. Interdependence of modules can have a direct bearing on the available means of successfully utilizing the `use` functionality. In certain situations, some of the ways to utilize the `use` statement can be problematic.

Some such situations, and workarounds, are illustrated below.

The basic description of the `use` statement functionality is,

Math is boring. Math isn’t useful. You’ll never need to use math again after school. It isn’t necessary to learn math, now that we have cash registers, calculators and computers. Math is just plain boring.

After ?invtrig:

For real arguments x, y, the two-argument function arctan(y, x), computes the principal value of the argument of the complex number x+I*y, so -Pi < arctan(y, x) <= Pi.

For any point in C or R^2 (x,y)<>(0,0) the geometrical meaning of this result is clear: the angle that the segment/vector from (0,0) to (x,y) forms with the x-axis. But this angle is undefined if this point is the origin.

So, what is arctan(0,0)?, and what it should be?

If x -1 is regarded as the difference of two cubes, can Maple factor it?

The attached work sheet teaches you the fundamental concepts behind the antiderivative.

The examples in this worksheet are entirely done in an interactive video tutorial - follow the link below:

Antiderivatives - Video Tutorial

Enjoy!

The attached worksheet is a wonderful introduction to the concept of obtaining the area under a curve.

You'll see how easy it is to learn how to find the limit of the sum of a series using Maple.

An interactive video tutorial that shows you how to do Riemann sums really fast is linked below:

Riemann Sums...

f := proc (x) options operator, arrow; cos(x)-x*sin(x)+1 end proc

_EnvAllSolutions := true

solutions := [solve(f(x) = 0, x)]

evalf({%})

What is up with that solution at zero?  And if this function is plotted, there is clearly a solution at around x=1.3.  Maple does not see this, is there a setting I missed?  Thanks.

GMP is now deeply integrated into Maple - which I consider to be a good thing.  But it appears that compiler writers are doing a bad job (see the first paragraph on GMP's home page)  In other words, unless you carefully make sure that you have compile GMP properly, it is entirely possible that you end up with a buggy library.  Very scary stuff.

It’s not the fault of my world-famous professors at M.I.T. who gave me a M.Sc. degree in Electrical Engineering, but it’s a fact – I know less about engineering than most (if not all) of you.

Way back then, “Computer Science” was a fledgling field of study, and in many schools it was an offshoot of either math or engineering.  In my case it was an offshoot of engineering, and ergo my inappropriate degree.

So much for my sordid past.

Can Maple graph the Dirichlet function?

f(x) =   {0,   if x is rational
            {1,   if x is irrational

Yesterday I watched a demonstration of Maple being applied to the modeling and simulation of the internal deformations of human bones. The researcher was a mathematician working primarily in the biomedical modeling fields. The actual technique was to utilize the symbolic mathematical power of Maple to formulate the necessary equation pieces for a finite element model (FEM) of the internals of the bone. The equations are then fed into the legendary FEM solver ABAQUS.

Due to the notoriously non-linear qualities of human flesh and bone, traditional formulation methods developed for modeling beams and metals simply do not work. So as in the case of so many impressive engineering applications, the power of Maple is being deployed in the formulation or the pre-solution phase of modeling and in doing so, previously infeasible models now become feasible.

Please.. Anybody explained this plot?

Thanks & Regards

Everything below is "as far as Maple is concerned".

The following indicates that infinity does not satisfy the property of being real.

> is(infinity,real);
                                     false

But this next pair indicates that infinity is real. They show that infinity satisfies the nonstrict inequality relation equivalent to the 'real' RealRange, from which it would follow that infinity is in the 'real' RealRange.
