Various cases of SOLVER hallucinations & failures

[Wiljea]

Two cases are presented, one here concerning one simple eqn taken from "Driven Damped Oscillations" using v 0.8.8. The other even simpler case is presented in the following comments.
@ Expecting [ m=2.04356 62331 4⁳³⁶ kg ]
@ Failing [ m=4.44444 44444 4⁳⁻² kg ]
@ This a simple case of total SOLVER hallucination
ω0=15_r/s k=10_N/m
'ROOT([(ω0_(r/s))=(1_r)*√((k_(N/m))/(m_kg))];[m];[1_kg])'

This type of relation appears at different places in "Waves" and forces MSOLVE to fail.

Just to indicate that the case "PN Step Junctions" was working in v0.8.7 but in v0.8.8, we now got a MSOLVE failure with the message: "Unable to solve for all variables" for absolutely no discernable reason. If you have any clue, you're welcome !

Here's a clue: it seems that the SIDENS function doesn't work OR even exist anymore !!

Done.
