 | | :''For other uses of the term calculus see calculus (disambiguation) Calculus is a branch of mathematics, developed from algebra and geometry, involving two major complementary ideas. |
 | | The first, called differential calculus, is a theory about rates of change, and involves the method of differentiation, which permits mathematical functions, velocity, acceleration, and slopes of curves at a given point all to be discussed on a common symbolic basis. |
 | | It is directly relevant to finding the maxima and minima of a function — because those are points at which the graph is (expected to be) flat. |
