Well, there are various tests that could go in the module. That's what's in the Maple Calculus of Variations package. What I'd like to see is the ability to take a variation. I've implemented something simple along these lines in Maple already. It's not particularly robust at the moment though. > It definitely shouldn't go in physics, since calculus of variations is useful > to more than just physics! I agree. The only other place it kind of fits is the integrals module, but that's not really right since the Euler-Lagrange equation is a differential equation, not an integral. I find the naming of that module somewhat unfortunate since I'd rather see a calculus module with integrals, ODEs, and PDEs in it. If that was the case, I'd put the calculus of variations stuff in there.
