CALCULUS

(mathematics) a way of making calculations about quantities which are continually changing, such as the speed of a falling stone or the slope of a curved line. Calculus measures little bits of things in order to find out what the whole thing will do. That is the whole theory of calculus. —Clearing Congress №3: The Freedoms of Clear Approved Glossary, —Scientology and Ability Glossary Final approval 18/9/89, —Ability Congress Approved Glossary
