Throughout numerical weather prediction, you often need to calculate the gradient of a function at a number of points. Use forward difference approximation of. A finite difference is a mathematical expression of the form f (x + b) − f (x + a).if a finite difference is divided by b − a, one gets a difference quotient.the approximation of derivatives.
