Two men on a 3-D surface want to meet each other. The surface is given by \(f(x,y)=\frac{x^{-6}.y^7}{x+y}\). They make their move horizontally or vertically with the X-Y plane as their reference. It was observed that one man was initially at (200, 400) and the other at (100, 100). Their meet point is decided as (0, 0). Given that they travel in straight lines, will they meet?

Partial Differentiation topics include: Limits and derivatives of variables, implicit and partial differentiation, eulers theorem, jacobians, quadrature, integral sign differentiation, total derivative, implicit partial differentiation and functional dependence. Partial differentiation is a mathematical process that finds the derivative of a function with respect to one of its variables, while holding the other variables constant. It's used in vector calculus and differential geometry. Partial differentiation is more general than ordinary differentiation, which finds the derivative with... Show more
