What is MakeRules (Option of Solve) good for?
Hi, MathGroup, looking for a way to find out about the substitutions, that were carried out during Solve, I found out that Solve has an option MakeRules, which defaults to False. I could not find anything on it, neither in THE BOOK nor in the online-help. Is anyone out there, who has used MakeRules? Has anyone found out a practical way to see the substitutions, that were made during Solve, e.g. when solving Solve[-(d*x) + (x + xx)*Sqrt[(-1 + n^2)*x^2 + n^2*z^2]==0,x] which yields a long solution set with over and over the same complicated subexpressions (probably from writing out some substitutions done during the Solve-Process). kind regards Dipl.-Math.
