Wolfram|Alpha Widgets: "Inverse of a 2x2 matrix A modulo n" - Free Mathematics Widget Inverse of a 2x2 matrix A modulo n Added Dec 26, 2013 by Martin Fitzpatrick in Mathematics The widget calculates the inverse of a 2x2 matrix modulo n.

Feb 16, 2021 · Modular arithmetic is the arithmetic of congruences, sometimes known informally as "clock arithmetic." In modular arithmetic, numbers "wrap around" upon reaching a given fixed quantity, which is known as the modulus (which would be 12 in the case of hours on a clock, or 60 in the case of minutes or seconds on a clock). Since this is tagged wolfram-mathematica I assume you are asking in the context of Mathematica, in which case there is a built-in function to do this: PowerMod[9,-1,m] This will give you the inverse of 9, modulo m, for whatever value of m you want. Table[PowerMod[9,-1,m],{m,2,1000}] will produce: Matrices are array of numbers or values represented in rows and columns. Inverse of a matrix A is the reverse of it, represented as A-1.Matrices, when multiplied by its inverse will give a resultant identity matrix. 3x3 identity matrices involves 3 rows and 3 columns. This visually illustrates various properties of modular arithmetic by creating an "operation table" modulo , where 0 is represented by black, 1 by white, and other values by intermediate colors. The allowed numbers can be restricted to be nonzero or the units modulo , and the operations are modular addition, subtraction, powers, and sums of Get the same capabilities as the public Wolfram|Alpha system—without accessing the external web.

Here are problems and the commands that are typed to solve them with Wolfram Alpha. (1) Reduce 13456 modulo 147: 13456 mod 147 (2) Find a solution to 14x+ 17y = 1 in Z: solve 14*x + 17*y = 1 in integers (3) Find the gcd of 1457 and 4277: gcd(1457,4277) (4) Compute 145 mod 29: 14^5 mod 29 (5) Find the inverse of 14 mod 29 (that is, solve 14x 1 \$\begingroup\$ You are right, wolfram alpha is wrong! \$\endgroup\$ – user3184807 Apr 1 '15 at 10:34 Finding multiplicative inverse modulo n using matrix method. 2.

\$\endgroup\$ – Henry T. Horton Jun 19 '13 at 21:08 InverseSeries[s] takes the series s, and gives a series for the inverse of the function represented by s. InverseSeries[s, x] uses the variable x in the inverse series. InverseFunction[f] represents the inverse of the function f, defined so that InverseFunction[f][y] gives the value of x for which f[x] is equal to y. InverseFunction[f, n, tot] represents the inverse with respect to the n\[Null]\[Null]^th argument when there are tot arguments in all. ### Use the Number Theory section for division, modular arithmetic, prime numbers, special numbers, and integer functions Do sequence computations like summation, product, and limit of a sequence Compute permutation and combinatorics questions, including derangements and permutations of list or finite relations and Pascal's triangle The main difference between this calculator and calculator Inverse matrix calculator is modular arithmetic. Modulo operation is used in all calculations, and division by determinant is replaced with multiplication by the modular multiplicative inverse of determinant, refer to Modular Multiplicative Inverse.

( w2 − x2). Jelikož víme, že a je liché a navíc w2 a x2 jsou modulo 4 kongruentní s 1 nebo 0, tak Pro počítání hodnot použijte Wolfram Alpha.

Wolfram Alpha is computing the modular inverse. That is, it's finding the integer x such that. exp*x == 1 mod (p - 1)* (q - 1) This is not the same as the modulo operator %. Here, Python is simply calculating the remainder when 1/exp is divided by (p - 1)* (q - 1) when given the expression in your question. 3.

InverseFunction[f] represents the inverse of the function f, defined so that InverseFunction[f][y] gives the value of x for which f[x] is equal to y. InverseFunction[f, n, tot] represents the inverse with respect to the n\[Null]\[Null]^th argument when there are tot arguments in all. Mod[m, n] gives the remainder on division of m by n. Mod[m, n, d] uses an offset d.
