Advanced methods often employ complex mathematical functions-such as logarithms, exponentiation, trigonometric functions and sophisticated statistical functions-to obtain the predictive characteristics desired.
From 1938 to 1946, 37 volumes of the NBS Math Tables Series were issued, containing tables of trigonometric functions, the exponential function, natural logarithms, probability functions, and related interpolation formulae (23).
