Enter the 4 values of a 2 x 2 matrix into the calculator. The calculator will evaluate and display the inverse of that matrix.
Inverse Matrix Formula
The following formula is used to calculate the inverse matrix value of the original 2×2 matrix.
First, the original matrix should be in the form below.
In this case, (ad-bc) is also known as the magnitude of the original matrix.
Inverse Matrix Definition
An inverse matrix is the reciprocal of a given matrix of a fixed number of rows and columns.
Inverse Matrix Example
How to calculate the inverse matrix
- First, set up your original 2×2 matrix
This should follow the form shown above, with a,b,c, and d being the variables.
- Next, calculate the magnitude
Calculate the magnitude of the first matrix use the formula a*d-b*c.
- Finally, calculate the inverse matrix
Calculate the inverse matrix using the magnitude and the formula above.
A matrix is a mathematical collection of values in a fixed number of rows and columns.
A matrix has many purposes, but it’s main use is for solving linear systems of equations.
