1. Graphing Quadratic Functions
Sign In
A matrix has an inverse if and only if its determinant is not zero.
& - 1/4 & & - 1/24 & & 0 & & 1/6 &
To find the inverse of the given 2* 2 matrix, we will use the corresponding formula.
Matrix | Inverse |
---|---|
A= [ cc a & b c & d ] | A^(- 1)=1/ad-bc [ cc d & - b - c & a ] where ad-bc ≠0 |
Substitute values
(- a)b = - ab
