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.

Chapter 4: Roundoff and Truncation Errors
isdl.cau.ac.krNumerical Differentiation The first order Taylor series can be used to calculate approximations to derivatives: Given: Then: This is termed a “forward” difference because it utilizes data at i and i+1 to estimate the derivative. f(x i 1) f(x i) f '(x i)h O(h 2) f'(x i) f(x i 1) f(x i) h O(h) 22
NumericalDifferentiation andIntegration - Forsiden
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.
Numerical Differentiation - Karen A. Kopecky
www.karenkopecky.netIn addition we can derive general second-order accurate approximations to f00 using weighted sums of f evaluated at various points, only now we would need 4 points instead of 3. In an analogous way to the f0 case we can use these (usually more costly) general formulas to handle special situations like approximating the second derivative at the boundary of the
