Інформаційні технології оцифровки графіків функції

Abstract

It is often necessary to obtain a table of values of its coordinates from the graph of a function. Most often, similar situations arise either during the analysis of literary data, when the results of research are presented in the form of a two-dimensional graph that is not provided with an appropriate analytical expression, or the corresponding graph is obtained with the help of specialized equipment as a result of conducting certain experiments. There are various options for solving such a problem, starting from purely "manual" without the use of a computer. The very operation of digitizing two-dimensional graphs is quite routine and cumbersome, so it is natural to search for ways to automate this procedure as much as possible. This work describes the method of using the free service, which helps to automate the specified process to a large extent.
