The study of computer-based mechanisms is based on the use of finite differences. The numerical derivation of the functions obtained in the analysis and synthesis of the mechanisms is much easier than the analytical derivation. Obtaining the elements of the functional matrix (Jacobian), corresponding to a system of nonlinear equations, with a large number of equations, is done only numerically. In this sense, finite differences are often used in numerical calculation. If a function is given in a table and it is required to calculate the derivative or integral of this function, formulas are used that use the finite differences.
