Dec 17, 2021 · Numerical differentiation is the process of finding the numerical value of a derivative of a given function at a given point. In general, numerical differentiation is more difficult than numerical integration. This is because while numerical integration requires only good continuity properties of the function being integrated, numerical differentiation requires more complicated properties such as Lipschitz classes.

Numerical Differentiation Differentiation is a basic mathematical operation with a wide range of applica-tions in many areas of science. It is therefore important to have good meth-ods to compute and manipulate derivatives. You probably learnt the basic rules of differentiation in school — symbolic methods suitable for pencil-and-paper calculations.

The 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 and k = 0.

Numerical 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. One method for numerically evaluating derivatives is to use Finite DIfferences: From the definition of a first derivative
