Can matrices be divided?
+
Matrices cannot be divided in the traditional sense. Instead, we find the inverse of a matrix and multiply by it to solve equations.
How do I know if a matrix has an inverse?
+
A matrix has an inverse if its determinant is not zero. For square matrices, this means the matrix is non-singular.
What does an eigenvector represent in the context of matrices?
+
An eigenvector represents a vector that doesn’t change direction when the matrix transformation is applied, only getting scaled by a scalar value known as the eigenvalue.
Are there any real-world applications of matrix inversion?
+
Yes, matrix inversion is used in applications like cryptography, optimization in operations research, solving systems of linear equations in electrical circuits, and more.
