Full Description:Desc: This program calculates the discriminant of a multi-variable function. When finding the extrema of a multi-variable function f(x,y), the discriminant at point (a,b) is calculated as Fxx(a,b)*Fyy(a,b)-Fxy(a,b)^2. Enter with parameters discrimi(f,a,b) to find the value of this discriminant.
