# Mathematical processes for computation

Chapter

## Abstract

We look first at the process of transferring from algebra to a computer language. We must begin by examining our chosen programming language to see what functions are supplied. Some languages such as Pascal are poor in supplied functions, and everything must be written afresh, but usually we have a good range, both of algebraic functions, like trigonometric functions – sines, tangents, cosines and their inverses – and also of manipulative functions, like maxima and minima, integer parts, etc. Note that there are minor dialectal differences, such as ATN or ATAN, SQR or SQRT, etc. which can cause delays in transcription.
