FLASHCARD QUESTION
Front
What is a matrix equation?
Back
A matrix equation is an equation in which the unknowns are matrices, and it can be expressed in the form [A][X] = [B], where [A] is a coefficient matrix, [X] is the matrix of variables, and [B] is the result matrix.

FLASHCARD QUESTION
Front
How do you solve a system of linear equations using matrices?
Back
You can solve a system of linear equations by representing it in matrix form [A][X] = [B] and then finding [X] by calculating [X] = [A]⁻¹[B], where [A]⁻¹ is the inverse of matrix [A].

FLASHCARD QUESTION
Front
What is the determinant of a matrix?
Back
The determinant is a scalar value that can be computed from the elements of a square matrix and provides important properties about the matrix, such as whether it is invertible.
