Yet Another Bug in Mathcad's Symbolics

[tietjee]

Is anyone tracking these YABIMSs?  Is it too much to expect PTC to track?

The symbolic engine in Prime is the same antiquated MuPad that was in Mathcad when PTC bought it. 

Nobody's tracking!  Nobody cares!  Nobody will fix them.

Unfortunately - no (first question) and yes (second one)!

PTC never was interested in bug reports.

This applies in particular to Mathcad and even more specifically to the symbolic kernel MuPad used there.

So Fred is perfectly right in his analysis - nobody at PTC cares, and the chance that such bugs will be fixed is close to zero.

Hello Werner_E

just an update - seems this bug is fixed in MP 9 !

My original post was about real Mathcad (version 15 and below), but the bug also was present in the first versions of Prime.

The bug was fixed in Prime 6 with the introduction of the new symbolic engine (Axiom/friCAS).

While the new engine generally seems to be less capable compared to the old one (muPad),  it does not suffer from some bugs the old engine had (but it has new bugs on the other side).

I'am closing this thread as nobody will fix bugs in older versions of Prime anymore, let alone in real Mathcad.
