Non Iterative & Signum-based Iterative methods - roots / maximum / mimimum - Messages

Non iterative methods for root estimation + iterative methods based on the sign(1) function for finding roots and maximum/minimum values in a range.

Thanks Davide ... that will make my day !
I discovered the "GID" transit integrator in Mathcad 11.
Works as well in Smath. Don't know if other CAS support ?
Then: like this

BTW: Nobody @ PTC Mathcad Community has seen "GID" integrator,
PTC and Jean ended "warflame" years ago before "GID" [just too bad].

... in your last example: there is a missing 0 and an extra min/max

True, thank you Jean
Usually it may need to play a little with bounds and intervals. In this case changing intervals from 40 to 41 fixed the issue. (updated the first post)
