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]
The Pappus configuration is the configuration of 9 lines and 9 points that occurs in Pappus's theorem, with each line meeting 3 of the points and each point meeting 3 lines. In general, the Pappus line does not pass through the point of intersection of A B C {\displaystyle ABC} and a b c {\displaystyle abc} . [ 3 ]
[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.
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.
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.
aleph-nought, aleph-zero, or aleph-null) is the cardinality of the set of all natural numbers, and is an infinite cardinal.The set of all finite ordinals, called or (where is the lowercase Greek letter omega), also has cardinality .
This formula can be used to compute () with floating point operations for real between 0 and 2.5. For x > 2.5 {\displaystyle x>2.5} , the result is inaccurate due to cancellation . A faster converging series was found by Ramanujan : [ 3 ]
For , a pseudoinverse of A is defined as a matrix + satisfying all of the following four criteria, known as the Moore–Penrose conditions: [4] [5] A A + {\displaystyle AA^{+}} need not be the general identity matrix, but it maps all column vectors of A to themselves: A A + A = A . {\displaystyle AA^{+}A=\;A.}
