In mathematics, the Hessian matrix or Hessian is a square matrix of second-order partial derivatives of a scalar-valued function, or scalar field.It describes the local curvature of a function of many variables. Also, be careful when you write fractions: 1/x^2 ln(x) is `1/x^2 ln(x)`, and 1/(x^2 ln(x)) is `1/(x^2 ln(x))`. The interval can be specified. If this option is set to true, the points a and b must be finite and are set to −10 and 10 if they are not provided.
