History of Calculus? - Answers

Calculus was start from the Greek Mathematicians. They started calculating the rise and run (slope) of curves and non straight lines. Zeno of Elea in 455 BC, discovered the concept of Infinity. Further contributions were made by Leucippus, Democritus, Antiphon and Eudoxus. Archimedes, was the first important person who showed advance to show that the area of a segment of a parabola is 4/3 the area of a triangle with the same base and vertex and 2/3 of the area of the circumscribed parallelogram. Among other 'integrations' by Archimedes were the volume and surface area of a sphere, the volume and area of a cone, the surface area of an ellipse, the volume of any segment of a paraboloid of revolution and a segment of an hyperboloid of revolution. Other important contributors were Huygens, Leibniz, Newton, Jacob, Johann, and many more. The father of Calculus in 19th Century is Cauchy, who completed the calculus and made the shape which today we see.
