George Brinton Thomas Jr. (January 11, 1914 – October 31, 2006) was an American mathematician and professor of mathematics at the Massachusetts Institute of Technology (MIT). Internationally, he is best known for being the author of the widely used calculus textbook Calculus and Analytic Geometry, known today as Thomas' Textbook.
for the infinite series. Note that if the function () is increasing, then the function () is decreasing and the above theorem applies.. Many textbooks require the function to be positive, [1] [2] [3] but this condition is not really necessary, since when is negative and decreasing both = and () diverge.
Calculus Made Easy ignores the use of limits with its epsilon-delta definition, replacing it with a method of approximating (to arbitrary precision) directly to the correct answer in the infinitesimal spirit of Leibniz, now formally justified in modern nonstandard analysis and smooth infinitesimal analysis.
Archimedes also discovers a method which is similar to differential calculus. [1] 3rd century BC - Archimedes develops a concept of the indivisibles—a precursor to infinitesimals—allowing him to solve several problems using methods now termed as integral calculus.
Thomas G. Goodwillie (born 1954) is an American mathematician and professor at Brown University who has made fundamental contributions to algebraic and geometric topology. He is especially famous for developing the concept of calculus of functors , often also named Goodwillie calculus .
15th: Rigorous foundation of Schubert's enumerative calculus. Partially resolved. [23] Haibao Duan and Xuezhi Zhao claimed that this problem is actually resolved. — 16th: Describe relative positions of ovals originating from a real algebraic curve and as limit cycles of a polynomial vector field on the plane.

In complex analysis, the residue theorem, sometimes called Cauchy's residue theorem, is a powerful tool to evaluate line integrals of analytic functions over closed curves; it can often be used to compute real integrals and infinite series as well.
