Born in England in January 4, 1643, son to a local farmer and labeled for his irrational behavior, is one of the greatest geniuses, Isaac Newton. Newton is known as one of the “Greatest minds of the 17th century Scientific Revolution”. Despite of his humble beginnings and difficult childhood he managed to go to school. The University of Cambridge fascinated him with the new science of the 17th century and intrigued him to learn more about modern philosophers. His curiosity for this new world in his studies took a break in 1665 when the Great Plague forced the university to close. Newton continued with his studies at home, and in this 18 month period he created the theory of light and color, the planetary motion and infinitesimal calculus. This creations were later published in his book”Philosophiae Naturalis Principia Mathematica” (“Principia” for short) is known for its great history of science for the next centuries. His theory was derived from theories from Englishmen such as John Wallis and Isaac Barrow along with Continental Mathematicians as Rene Descartes, Pierre de Fermat, Gilles Personne de Roberval, Johann van Waveren Hudde, and Bonaventura Cavaleri. This introduction to calculus facilitated

Newton had already stated that to find the slope at any point of the function it would be f(x) but the slope of a curve would constantly change. To calculate this, the term differential calculus or differentiation was used. Newton’s preferred the name of ‘methods of fluxions” since “fluxion” is the instantaneous rate of change in appoint on the curve but the “fluents” were the changing values of x and y which later changed to “methods of fluents”. Some derivate functions were found such as the exponential and logarithmic functions and trigonometric functions such as sin(x), cos(x), tan (x) etc. So that a derivative function can be used in any
