MATH.7:4.6 - Revisit only what the changed question uses

When h changes, derive the affected receiving operations and constants again. When the question adds a quantity or relation, construct its receiving form even if the earlier operations are unchanged. When a domain restriction changes, revisit both inverse equations and the allowed operation inputs.

Return a failed equation or two source cases that the map cannot distinguish through MATH.6 or MATH.2 as appropriate. Use C.29 when the mathematical representation is being related to another subject. Stop with the needed calculation, reusable transported structure, or identified obstruction.
