2nd order partial derivative C ++. Mixed partial derivative Numerical differentiation.
Numerical differentiation - a set of methods for calculating the value of the derivative of a discrete given function.
Separately, it should be noted the case of the numerical determination of partial differentials of functions of several variables. In this case, all the arguments of the function become constants except the argument, according to which differentiation is carried out, and the required order of the derivative is obtained by sequentially calculating the derivatives, up to the required order. When calculating high-order derivatives, the derivative of the (n) -th order is considered the first derivative of the (n-1) -th order. So the second derivative of the function is the first derivative of the first derivative.
