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]
Suppose we wish to determine if n = 221 is prime. We write (n−1)/2=110. We randomly select an a (greater than 1 and smaller than n): 47. Using an efficient method for raising a number to a power (mod n) such as binary exponentiation, we compute: a (n−1)/2 mod n = 47 110 mod 221 = −1 mod 221
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.
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 ]
[3] [4] [5] If the operator is originally given by a square matrix M , then its Jordan normal form is also called the Jordan normal form of M . Any square matrix has a Jordan normal form if the field of coefficients is extended to one containing all the eigenvalues of the matrix.
The element of this subspace that has the smallest length (that is, is closest to the origin) is the answer + we are looking for. It can be found by taking an arbitrary member of A − 1 ( { p ( b ) } ) {\displaystyle A^{-1}(\{p(b)\})} and projecting it orthogonally onto the orthogonal complement of the kernel of A ...
The first major result was that of John von Neumann in 1933, [3] giving an affirmative answer for compact groups. The locally compact abelian group case was solved in 1934 by Lev Pontryagin . The final resolution, at least in the interpretation of what Hilbert meant given above, came with the work of Andrew Gleason , Deane Montgomery and Leo ...
