Conclusion: In saddle points calculus, a saddle point or minimax point is a point on the surface of the graph for a function where the slopes in perpendicular directions become zero (acritical point), but which is not a local extremum of the function. Mathematicians and engineers always have to find saddle point when doing an analysis of a surface.

Example 1 Determine the critical points and locate any relative minima, maxima and saddle points of function f defined by f(x , y) = 2x 2 + 2xy + 2y 2 - 6x Solution to Example 1: Find the first partial derivatives f x and f y. f x (x,y) = 4x + 2y - 6 f y (x,y) = 2x + 4y The critical points satisfy the equations f x (x,y) = 0 and f y (x,y) = 0 simultaneously. Hence

A Quick Refresher on Derivatives. A derivative basically finds the slope of a function.. In the previous example we took this: h = 3 + 14t − 5t 2. and came up with this derivative: ddt h = 0 + 14 − 5(2t) = 14 − 10t. Which tells us the slope of the function at any time t. We used these Derivative Rules:. The slope of a constant value (like 3) is 0; The slope of a line like 2x is 2, so 14t ...
