The branch that grew out of the calculus of Newton and Leibniz: the rigorous study of limits, continuity, differentiation, integration and infinite series. Nineteenth century mathematicians (Cauchy, Weierstrass, Riemann) re-founded calculus on precise epsilon-delta definitions of limit, replacing the informal infinitesimals of the subject's founders with a fully rigorous apparatus that still underlies real and complex analysis today. Two centuries before Newton and Leibniz, the Kerala school of astronomy and mathematics in southern India, working from Madhava of Sangamagrama (c. 1340 to c. 1425) onward, derived infinite series for sine, cosine and arctangent equivalent to what are now called Taylor series, apparently without the wider theory built around them in Europe and without influencing the European tradition, so far as surviving evidence shows; whether any transmission route to Europe existed is a live historical question rather than an established fact.
Facts
Central QuestionHow do quantities behave in the limit, continuously and infinitesimally, and what does it mean, rigorously, for an infinite process to converge? 2 Key DebateWhether the nineteenth century's rigorous epsilon-delta re-founding of calculus rescued the subject from genuine paradox in Newton and Leibniz's original infinitesimals, or merely papered over an intuition that Abraham Robinson's nonstandard analysis later showed could itself be made fully rigorous. 2 Classification

Historically, applied mathematics consisted principally of applied analysis, most notably differential equations; approximation theory (broadly construed, to include representations, asymptotic methods, variational methods, and numerical analysis); and applied probability.

It seems clear that Pythagoras would have thought of 1, 2, 3, 4, ... (the natural numbers in the terminology of today) in a geometrical way, not as lengths of a line as we do, but rather in the form of discrete points.
