Survey of formula manipulation

Abstract

The field of formula manipulation is surveyed, with particular attention to the specific capabilities of difFerentiation, integration and the supporting capabilities of simplification, displays and input/output editing, and precision arithmetic. General systems--both batch and online-ore described. Finally, some programs to solve specific applications are discussed.

“…The notion of programming with natural language is not new (having first been described by Sammet in 1966 [15]). Begel further described the diverse ways in which spoken language can be used in software development [2].…”

Computer Algebra: from the Visible to the Invisible

“…It was precisely for reasons like this that algebraic computing first came into existence. In the words of Jean Sammett in a general review article on the emerging field in 1966 [4] 'It has become obvious that there are a large number of problems requiring very tedious, time-consuming, error-prone and straightforward…”
