This algebra 2 math tutorial from NutshellMath offers help with inverse matrices and how to find them. A matrix is a mathematical tool used to organize a set of data. Matrices have their own rules and properties. One such property is that of inverse matrices. Two matrices can be considered inverse matrices if their product in either order of multiplication is the identity matrix.
This tutorial gives a formula for finding the inverse of a 2x2 matrix, and offers examples of how to find them. In order to find the inverse, it is necessary to plug in the appropriate values from the first matrix into the formula for the second, paying attention to signs, and properly distributing coefficients. Not all matrices have inverses. For 2x2 matrices, if the difference between the products of the diagonal entries equals zero, then the matrix has no inverse. To verify that two matrices are inverse matrices of each other, simply multiply the two together and check that the result is the identity matrix.
Matrices are powerful algebraic tools to be used in solving a variety of problems. In multiplying matrices, it is useful to understand and be able to apply inverse matrices.
