Hi, While there's probably an easy answer to my question, I couldn't find it in the texts and online resources that I looked at. I've got a optimization problem, with functional forms that looks like: UK = Uk[ xk, Lk] UJ = Uj[ xj, Lj] Vk = Vk[ wk, Ak] Vj = Vk[ wk, Ak] where xj = wj T + Aj - wj Lj + ... other elements xk = wk T + Ak + wK Lk + ... other elements This sets up a objective function that I mazimize: (Uk - Vk) (Uj - Vj) When I was using v3 of Mathematica, the First Order Conditions were in a format of Uk (0,1) where (0,1) was a superscript. I've come back to this problem after a little hiatus, upgraded to v4, and I get derivatves in a more traditional format, [done w.r.t Lk] with dUk as a numerator, and an expression (dAk - Lk wk + Twk -...) as a denominator. Is there some way to switch back to the old representation? Did I miss something? Thanks. Richard Simmons
