I got the partial derivatives df/dx=y-e^x and df/dy=x-e^x, but i do not know how to solve for any of the variables... |

Given: f(x, y) = x*y - exp(x) The critical point exists at a set of values of x and y where both partial derivatives equal zero. df/dx = 0 df/dy = 0 Thus: y - exp(x) = 0 x - exp(x) = 0 Unfortunately, there is no solution in terms of elementary functions. This is an ugly one, where we are stuck with a non-analytic solution. My Computer Algebra Software recommends that x=-LambertW(-1). I've never even heard of Lambert functions in my life. Even more unfortunate, there is no real number solution to x = exp(x). Plot a simple graph of both functions, and you will see no ordinary intersection. Conclusion: there isn't any critical point for this particular function, if you are limited to the real number domain of x and y.
