Chapter 9: Numerical Differentiation - Purdue University
www.cs.purdue.eduNumerical Differentiation Formulation of equations for physical problems often involve derivatives (rate-of-change quantities, such as v elocity and acceleration). Numerical solution of such problems involves numerical evaluation of the derivatives.

NumericalDifferentiation andIntegration
www.uio.noLet 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.
Chapter 5: Numerical Integration and Differentiation
www.ece.mcmaster.caChapter 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. I = Z b a f(x)dx … Z b a fn(x)dx where fn(x) = a0 +a1x+a2x2 +:::+anxn. 1 The ...
5 Numerical Differentiation
www2.math.umd.eduThe numerical differentiation formula, (5.9), then becomes f0(x k) = Xn j=0 f(x j)l0 j (x k)+ 1 (n+1)! f(n+1)(ξ x k) Y j=0 j6= k (x k −x j). (5.10) We refer to the formula (5.10) as a differentiation by interpolation algorithm. Example 5.1 We demonstrate how to use the differentiation by integration formula (5.10) in the case where n = 1 ...

homepage.divms.uiowa.eduNumerical methods vary in their behavior, and the many different types of differ-ential equation problems affect the performanceof numerical methods in a variety of ways. An excellent book for “real world” examples of solving differential equations is that of Shampine, Gladwell, and Thompson [74].
