Symbolab is an answer engine [1] that provides step-by-step solutions to mathematical problems in a range of subjects. [2] It was originally developed by Israeli start-up company EqsQuest Ltd., under whom it was released for public use in 2011. In 2020, the company was acquired by American educational technology website Course Hero. [3] [4]
Microsoft Math Solver (formerly Microsoft Mathematics and Microsoft Math) is an entry-level educational app that solves math and science problems.Developed and maintained by Microsoft, it is primarily targeted at students as a learning tool.
WolframAlpha gathers data from academic and commercial websites such as the CIA's The World Factbook, the United States Geological Survey, a Cornell University Library publication called All About Birds, Chambers Biographical Dictionary, Dow Jones, the Catalogue of Life, [1] CrunchBase, [10] Best Buy, [11] and the FAA to answer queries.
A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.
a (n−1)/2 mod n = 2 110 mod 221 = 30 mod 221 mod n = () mod 221 = −1 mod 221. Hence 2 is an Euler witness for the compositeness of 221, and 47 was in fact an Euler liar. Note that this tells us nothing about the prime factors of 221, which are actually 13 and 17.
For example, more than 40 terms are required to get an answer correct to three significant figures for (). [4] However, for positive values of x, there is a divergent series approximation that can be obtained by integrating x e x E 1 ( x ) {\displaystyle xe^{x}E_{1}(x)} by parts: [ 5 ]
GeoGebra (a portmanteau of geometry and algebra) is an interactive geometry, algebra, statistics and calculus application, intended for learning and teaching mathematics and science from primary school to university level.
Third kind: An integral equation is called an integral equation of the third kind if it is a linear Integral equation of the following form: [3] () + (,) = where g(t) vanishes at least once in the interval [a,b] [4] [5] or where g(t) vanishes at a finite number of points in (a,b).
