Each of these can be verified by a proof based on the definitions given above. We present this only for the first two assertions in the list, to show the nature of the proofs.
In either case, Po is the center of an open ball that is a subset of A or a subset of B, since A and B are themselves open and Po must be interior to one of them. The proof that A n B is open is slightly different.
In the same way. Let Ii be the smaller of Ihe two numbers 15 1 , il 2. An B is open. Such detailed verbal arguments are tedious when carried to an extreme, The cssence of the second can be conveyed by the diagram given in Fig, , showing the step involving the two open balls.
Note, for example, that Ihis same diagram supplies the argument supporling tbe following stalement: Jf. I l are neiyhhorhOOlls of p,. We choose 10 discuss ii further, however, because it brings in something new.
We wish to prove that their union. The argument differs lillie from Ihal used for a finile collection. If pEA, then Ihere is at least one of Ihe sets. Since that set is open, p is surrounded by a ball which lies entirely inside A l ; however, this ball will also be a subset of A, since Al c A, and p is therefore interior to A, which IllUSt then be open.
Note thaI this argument does not really depend on having a cOllnlahtt' collection of open sets; thus, we are juslified in saying that the union of any collection of open sets is open.
The second half of assertion ii states that we cannot prove the corrcsponding assertion for the intersection of open sets.
To show this. It is instructive to sec where the proof for a finite collection of open sets breaks down. The purpose of such a list of topological facts and definitions is to give a language in which to describe new aspects of sets and functions with mathematical precision.
As an illustration of this. With enough samples.
In fact. Madhava of Sangamagrama and the Kerala School of Astronomy and Mathematics thereby stated components of calculus. A complete theory encompassing these components is now well known in the Western world as the Taylor series or infinite series approximations. I think it defines more unequivocally than anything else the inception of modern mathematics, and the system of mathematical analysis, which is its logical development, still constitutes the greatest technical advance in exact thinking.
The ideas were similar to Archimedes' in The Method , but this treatise is believed to have been lost in the 13th century, and was only rediscovered in the early 20th century, and so would have been unknown to Cavalieri. Cavalieri's work was not well respected since his methods could lead to erroneous results, and the infinitesimal quantities he introduced were disreputable at first.
The formal study of calculus brought together Cavalieri's infinitesimals with the calculus of finite differences developed in Europe at around the same time. Pierre de Fermat , claiming that he borrowed from Diophantus , introduced the concept of adequality , which represented equality up to an infinitesimal error term.
Isaac Newton developed the use of calculus in his laws of motion and gravitation. The product rule and chain rule ,  the notions of higher derivatives and Taylor series ,  and of analytic functions [ citation needed ] were introduced by Isaac Newton in an idiosyncratic notation which he used to solve problems of mathematical physics.
In his works, Newton rephrased his ideas to suit the mathematical idiom of the time, replacing calculations with infinitesimals by equivalent geometrical arguments which were considered beyond reproach.
He used the methods of calculus to solve the problem of planetary motion, the shape of the surface of a rotating fluid, the oblateness of the earth, the motion of a weight sliding on a cycloid , and many other problems discussed in his Principia Mathematica In other work, he developed series expansions for functions, including fractional and irrational powers, and it was clear that he understood the principles of the Taylor series.
He did not publish all these discoveries, and at this time infinitesimal methods were still considered disreputable. Gottfried Wilhelm Leibniz was the first to state clearly the rules of calculus. These ideas were arranged into a true calculus of infinitesimals by Gottfried Wilhelm Leibniz , who was originally accused of plagiarism by Newton.
His contribution was to provide a clear set of rules for working with infinitesimal quantities, allowing the computation of second and higher derivatives, and providing the product rule and chain rule , in their differential and integral forms.
Unlike Newton, Leibniz paid a lot of attention to the formalism, often spending days determining appropriate symbols for concepts. Today, Leibniz and Newton are usually both given credit for independently inventing and developing calculus. Newton was the first to apply calculus to general physics and Leibniz developed much of the notation used in calculus today.
The basic insights that both Newton and Leibniz provided were the laws of differentiation and integration, second and higher derivatives, and the notion of an approximating polynomial series. By Newton's time, the fundamental theorem of calculus was known. Table of contents Preface. PART I. Real Numbers and Limits of Sequences. Continuous Functions.
