The work describes the basics of processing courses aimed at differentiating them numerically. The most frequently applied methods of numerical differentiation have been classified and analyzed. The first is the application of a numerical differentiation estimator and the smoothing filter; the second - approximation of the differentiated course in the area of an independent variable, for which a derivative is being determined; and the determination of the derivative in an analytical way. Methods have been compared according to the explicitness criterion of solving the task of numerical differentiation .. The considerations have been illustrated with examples of differentiating the course of cylindrical pressureandtheir analysis.
