Hello Forum,(adsbygoogle = window.adsbygoogle || []).push({});

I think I am clear on how to find the maxima and minima of function of one or two independent variables like f(x) or f(x,y). What if the function had 5 independent variables, i.e. f(x,y,z,a,b)? What is the best method, even numerically? Should we find the partial derivatives of f w.r.t. to each variables and set them to zero? We would get a set of 5 equations. Then what?

Thanks in advance,
