Differential calculus is about finding the slope of a tangent to the graph of a function, or equivalently, differential calculus is about finding the rate of change of one quantity with respect to another quantity. In mathematics, differential calculus is a subfield of calculus concerned with the study of the rates at which quantities change.‎History of differentiation · ‎Applications of derivatives · ‎Physics · ‎Differential equations.

A closely related notion is the differential of a function. When x and y are real variables, the derivative differential calculus f at x is the slope of the tangent line to the graph of f at x.


Because the source and target of f are one-dimensional, the derivative of f is a real number. If x and y are vectors, then the best linear approximation to the graph differential calculus f depends on how f changes in several directions at once.

Differential calculus linearization of f in all directions at once is called the total derivative.


History of differentiation[ edit ] Main article: History of calculus The concept of a derivative in the sense of a tangent line is a very old one, familiar to Greek geometers such as Euclid c. The use of infinitesimals to study rates of change can be found in Indian mathematicsperhaps as early as AD, when the astronomer and mathematician Aryabhata — used infinitesimals to study the motion of the moon.

Rashed's conclusion has been contested by other scholars, however, who argue that he could have obtained the result by other methods which do not require the derivative of the function differential calculus be known. The key insight, however, that earned them this credit, was the fundamental theorem of calculus relating differentiation and integration: It is this which marks the most enormous of all contradictions Hermann, to be far from experimental sense data, with a metaphysics of infinity, the realization that the space between the chord of a circle and a segment of its attached arc can be divided infinitely, returns one to corpuscular philosophy and to the modern debate over whether matter is infinitely divisible.

This metaphysics arising out of the infinitesimal being matched to the physical world prepares the non-Euclidian features of Leibnizian topology and its recursive folds to become a tool of philosophy.


Here the symbols of mathematics are made concrete and therefore become usable by the empiricist. The supposition he has made, is only that differential calculus a momentary hypothesis for abbreviating the process and rendering it simpler.

He has done no other thing than to apply the calculus to the method of exhaustion of the ancients, that is to say, to the method of finding the limits of relations. Also, this great Philosopher, he never differentiates quantities, but equations, since every equation is expressed as a relation between two indeterminates, and so to differentiate an equation is to find the limits of the relation between the finite differences of the two indeterminates contained in the equation.

Differential calculus is particular to similar equations for the geometrical figure D'Alembert discusses figure 3, analys. The area y times y is equal to the area a [an arc bridging two sides of the triangle] times x [the shortest side of the triangle].

A way to conceive of this relation is as differential calculus angles differential calculus an equal slope in their current position. It holds that if m gets closer to M, then logically, R will similarly get closer to Q, changing its slope but keeping it equally to a similarly changed slope of mM.

So if the slope of is known, then the relation between Om as an ordinate and mM will hold for. Then dividing both sides by u equals.

The differential of yy is 2y or 2ydy. Solving for dy,so subsequently dividing each side of the equation by differential calculus, we have. Qualitatively, perhaps something like.
