Hi, I'm new at Maple, trying to migrate from Mathcad but I'm getting stuck on a basic problem. I want Maple to find numeric solutions to a maximization problem and express the solution as a function of the problem's parameters. To take a very simple example of the more general thing I want to do, suppose I have a profit function which is a function of inputs T and L and factor prices w and r. F:=(T,L)->T^(1/2)*L^(4/5); Profit := (T, L, w, r) -> F(T, L)-w*L-r*T; I seem to be able to almost isolate the parameterized functions I want as follows:
