It is not possible to uniquely determine M(x,y) from N(x,y) given the equation N(x,y)^M(x,y) - M(x,y)*e^N(x,y) = 0, as there is one equation with two unknowns. The discussion emphasizes that since M(x,y) depends on both x and y, the lack of additional equations limits the ability to solve for M(x,y). The context is part of a larger differential equation problem. Therefore, without further information or constraints, a unique solution for M(x,y) cannot be achieved.

Homework Statement



is it possible to find M(x,y) if I know N(x,y) and the equation i need to solve is N(x,y)^M(x,y) - M(x,y)*e^N(x,y) = 0?

both are linear functions

thanks, this is part of a longer differential equation and the above equations is what I end up with. Just need some input please.

Thanks!

If M(x,y) is in terms of both x and y then I would say no, because you only have one equation and two unknowns

What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
