Maple bugs: Thomas Richard: Hurrah, Maple quality improves!  Example 8

Hi Maple customers all over the world,
Get the answer in Maple 9.5.2 spending 60+ more time... enjoy its 1300+ times increased length, now 183 full screens, at the 1024x768 resolution, in standard math I/O mode, as compared with Maple 9.03.
As we already know well from Herr Richard, Maple Support, Scientific Computers GmbH:
Maple's quality improves... well... at least it does not deteriorate...

The same aria is sung by Laurent Bernardin, Chief Scientist & VP, Research who claims:

LB> Being strict about backwards compatibility can be frustrating LB> for our developers. A common comment I hear, is: "It would LB> really be easier to make this command work better, if I would LB> not have to worry about compatibility". This is a good sign. LB> It means the issue is taken seriously at all levels. It also LB> means that we are finding ways to move Maple forward and LB> improve the system without breaking existing user code.
And all this stuff is coordinated fragments of the 'Our Quality Is Superior' soap opera by Maplesoft...

Maplesoft> "Maplesoft technologies are ideal for students enrolled Maplesoft> in any math, science or engineering course. Learn how Maplesoft> you can use Maple to save time, learn more and became a Maplesoft> dropout, oh jeeeeezzz! we meant improve your grades."
Here is yet another way Maple quality improves... The silly users shamelessly name this a regression bug  we need here in Maplesoft a special educational project to grow the Maple superhero breed, enjoy A day of a CAS superhero at

Just an idea... press and hold the PageDown key to enjoy the scrolling over the output during about 1 minute (!)
