    1. What's Hessian matrix ?

    2. How Hessian matrix was derived ?

    1. I hate latex, so for a function of n variables, f(x1,...,xn) which is differentiable twice the hessian of the function is defined as


    2. It is a definition, it is not derived, however, there are some cool theorems with it such as an application to critical points.

    3. Any GOOD book on multivariable and vector calculus.

    To Pinu7~

    Thank ur replying ~

    And the reason I want to ask Hessian was that I heard that Hessian Matrix can be used while proving Taylor's expension for multivariable

    How come is that ??
