Historically, the concept of a proof and its associated mathematical rigour first appeared in Greek mathematics, most notably in Euclid's Elements. The problem of integer factorization, for example, which goes back to Euclid in 300 BC, had no practical application before its use in the RSA cryptosystem, now widely used for the security of computer networks. Other areas are developed independently from any application (and are therefore called pure mathematics), but often later find practical applications. Some areas of mathematics, such as statistics and game theory, are developed in close correlation with their applications and are often grouped under applied mathematics. Although mathematics is extensively used for modeling phenomena, the fundamental truths of mathematics are independent from any scientific experimentation. Mathematics is essential in the natural sciences, engineering, medicine, finance, computer science and the social sciences. These results include previously proved theorems, axioms, and-in case of abstraction from nature-some basic properties that are considered true starting points of the theory under consideration. A proof consists of a succession of applications of deductive rules to already established results. These objects consist of either abstractions from nature or-in modern mathematics-entities that are stipulated to have certain properties, called axioms. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. There is no general consensus among mathematicians about a common definition for their academic discipline. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively.

We are open to collaborations of all types, please contact Andy at for all enquiries. The clear explanations, strong visuals mixed with dry humor regularly get millions of views. Andymath content has a unique approach to presenting mathematics. Visit me on Youtube, Tiktok, Instagram and Facebook. In the future, I hope to add Physics and Linear Algebra content. Topics cover Elementary Math, Middle School, Algebra, Geometry, Algebra 2/Pre-calculus/Trig, Calculus and Probability/Statistics. If you have any requests for additional content, please contact Andy at He will promptly add the content. These concepts build upon foundational knowledge of algebra and trigonometry and are used to understand and analyze the behavior of functions.Ī is a free math website with the mission of helping students, teachers and tutors find helpful notes, useful sample problems with answers including step by step solutions, and other related materials to supplement classroom learning. Piecewise functions, limits, and continuity are typically studied in advanced math courses, such as calculus or analysis. Continuity is important for understanding how a function behaves and for making predictions about its values. A function is considered continuous if it can be drawn without lifting the pen from the paper. Limits are a fundamental concept in calculus that describe the behavior of a function as the input approaches a particular value.Ĭontinuity is another important concept in calculus that refers to the smoothness of a function. In Summary Piecewise functions can be helpful for modeling real-world situations where a function behaves differently over different intervals.
