ABSTRACT
Many problems arising in engineering require evaluation of real-valued functions. Evaluation of some of the commonly used functions, such as cos(x), on a computer usually utilizes the so-called lookup tables, which store a finite set of numbers describing the function of interest in a way that allows one to approximate the value of f(x) for any given x with a high level of accuracy. For example, a finite set of coefficients in the power series decomposition of f(x) could be used for this purpose.
