In the Middle East, Hasan Ibn al-Haytham, Latinized as Alhazen ( c. Medieval Middle East Ibn al-Haytham, 11th-century Arab mathematician and physicist In the 5th century AD, Zu Gengzhi, son of Zu Chongzhi, established a method that would later be called Cavalieri's principle to find the volume of a sphere. The method of exhaustion was later discovered independently in China by Liu Hui in the 3rd century AD to find the area of a circle. In The Method of Mechanical Theorems he describes, for example, calculating the center of gravity of a solid hemisphere, the center of gravity of a frustum of a circular paraboloid, and the area of a region bounded by a parabola and one of its secant lines. 212 BC), who combined it with a concept of the indivisibles-a precursor to infinitesimals-allowing him to solve several problems now treated by integral calculus. 390 – 337 BC) developed the method of exhaustion to prove the formulas for cone and pyramid volumes.ĭuring the Hellenistic period, this method was further developed by Archimedes ( c. Laying the foundations for integral calculus and foreshadowing the concept of the limit, ancient Greek mathematician Eudoxus of Cnidus ( c. See also: Greek mathematics Archimedes used the method of exhaustion to calculate the area under a parabola in his work Quadrature of the Parabola. Furthermore, the term 'calculus' has variously been applied in ethics and philosophy, for such systems as Bentham's felicific calculus, and the ethical calculus. Examples of this convention include propositional calculus, Ricci calculus, calculus of variations, lambda calculus, and process calculus. In addition to differential calculus and integral calculus, the term is also used for naming specific methods of calculation and related theories that seek to model a particular concept in terms of mathematics. In this sense, it was used in English at least as early as 1672, several years before the publications of Leibniz and Newton. Because such pebbles were used for counting out distances, tallying votes, and doing abacus arithmetic, the word came to mean a method of computation.

The word calculus is Latin for 'small pebble' (the diminutive of calx, meaning 'stone'), a meaning which still persists in medicine. In mathematics education, calculus denotes courses of elementary mathematical analysis, which are mainly devoted to the study of functions and limits.

Look up calculus in Wiktionary, the free dictionary. Today, calculus has widespread uses in science, engineering, and social science. Later work, including codifying the idea of limits, put these developments on a more solid conceptual footing. Infinitesimal calculus was developed independently in the late 17th century by Isaac Newton and Gottfried Wilhelm Leibniz.

These two branches are related to each other by the fundamental theorem of calculus, and they make use of the fundamental notions of convergence of infinite sequences and infinite series to a well-defined limit. The former concerns instantaneous rates of change, and the slopes of curves, while the latter concerns accumulation of quantities, and areas under or between curves. Originally called infinitesimal calculus or 'the calculus of infinitesimals', it has two major branches, differential calculus and integral calculus.

I find my son's ability to concentrate improved a lot in the last 3 months and I would like to continue this course as this helps in studies as well.Calculus is the mathematical study of continuous change, in the same way that geometry is the study of shape, and algebra is the study of generalizations of arithmetic operations.

I am amazed by the positive change in his results. His concentration in studies has also improved a lot.

My son’s speed of solving mathematical sums has increased rapidly after joining Roots abacus centre.

She has developed more confidence and has started taking interest in studies. My daughter has improved a lot in maths and other subjects, ever since she joined Roots.His ability to analyze and solve problems accelerates in a big way. He doesn’t hesitate while doing different topics. My son is learning abacus since 8 months and I’ve seen drastic change in him.Roots has really helped my child to fall in love with maths, thanks to the excellent faculty, maths is no more like a torture to my daughter now.
