In this video, we will see how to check whether, at the critical points, which we get with the help of partial derivatives, the function is taking maximum, minimum value or its a saddle point.
With the help of Hessain matrix and principal minors, we will see that it's very easy to find the nature of function at the critical points.
We will generalize the notion of Hessian and principal minors from 2x2 order to nxn order. Its a very simple extension and easy pattern to remember.
