## choices for integral form...

Maple

On the main page for the Rubi rule-based integrator, there is a table comparing results of Rubi against Maple and Mathematica.

On the face of it, the Maple results don't look so good. Maple is claimed as scoring about 82% correct on the author's example test suite. But only 42% of the suite gets an "optimal" result from Maple. The other 40% that Maple is claimed to get correct have results that are described as "Messy:

## threshold for ignoring nonreal part in p...

Maple

On the usenet newsgroup sci.math.symbolic Prof. Richard Fateman posted a question (or here) recently about what mechanisms a math application could use to handle the situation of negligible imaginary parts of computed data when plotting.

An example could...

## 2DMath in Mapleprimes...

Maple

Here's my first attempt at posting some 2DMath on this site.

First, I will paste directly from 2D output in a running Standard GUI Maple session.

BesselJ(0, x)+GAMMA(Psi)-sqrt(abs(omega))

Maple

Am I missing some justification for this last one?

## paranoia in maple...

Is anyone aware of Maple code intended to do some of the floating-point stress tests like are done in Kahan's paranoia code? (See here.)

I realize that modern Maple claims to comply with IEEE 854, 754, etc. But I like to check some things for myself. Call me paranoid. ;)
