Numerical Differentiation The problem of numerical differentiation is: • Given some discrete numerical data for a function y(x), develop a numerical approximation for the derivative of the function y’(x) We shall see that the solution to this problem is closely related to curve fitting regardless of whether the data is smooth or noisy

Let us first make it clear what numerical differentiation is. Problem 11.1 (Numerical differentiation). Let f be a given function that is only known at a number of isolated points. The problem of numerical differ-entiation is to compute an approximation to the derivative f 0 of f by suitable combinations of the known values of f.

Differentiation . Numerical differentiation serves to determine the local slope of the data, dy/dx. Fig. 1 shows a sample data set consisting of 7 data points, and shows how the individual points will be referenced. Fig. 1. Reference labels for data points when performing numerical differentiation and integration.

Chapter 5: Numerical Integration and Differentiation PART I: Numerical Integration Newton-Cotes Integration Formulas The idea of Newton-Cotes formulas is to replace a complicated function or tabu-lated data with an approximating function that is easy to integrate.
