Inspired by Rearick's work on logarithm and exponential functions of arithmetic functions, we introduce two new operators, LOG and EXP. The LOG operates on generalized Fibonacci polynomials giving ...

Thus all that need be said of Mr. Castle's tables (i) is that they seem to contain what the usual student requires, including hyperbolic logarithms, and exponential and hyperbolic functions.

It is a Math and Trigonometry functions function that performs mathematical calculations, including basic arithmetic, conditional sums and products, exponents and logarithms, and trigonometric ratios.

But as you mature in this world, you realize that topics like logarithms and exponential functions do have uses.
