This is inversing a functionExcel "Target value" is more ancient than Excel. In fact, it comes fromthe co-founders of Excel TKsolver.For single value of 'y' you can use Smath solve(2), solve(4) ...Otherwise, if you want to InverseFunction it comes from Smath/Maple.Visit "Samples" for a huge Smath document that covers most possibleways of doing this most advanced piece of maths.This document is less than 3 weeks old.

Boolean condition can be formed by using Boolean palette. Here is a simple example, returning numeric or symbolic result.https://smath.com/wiki/i...utoDetectCookieSupport=1
