In this booklet we shall consider some simple methods of plotting graphs from given formulas. We shall be dealing here with graphs of a different kind, with graphs that must be plotted from given mathematical formulas. A need for such graphs often arises in various fields of knowledge. Thus, in analysing the theoretical course of some physical process, a scientist obtains a formula yielding some magnitude with which he is concerned, for example, the amount of product obtained relative to time. The graph plotted from this formula will provide a clear picture of the future process. Looking at it, the scientist may possibly introduce substantial changes into the scheme of his experiment in order to obtain better results.
