  2. What are the conditions for two matrices to be inverses of each other?
  3. How do you find the inverse of a matrix?
  4. What is the significance of the identity matrix in matrix multiplication?
  5. Can two non-square matrices be inverses?

Tip: If the product of two matrices is the identity matrix, they are inverses of each other.

Formulas

Matrix Multiplication: If A = [a11, a12; a21, a22] and B = [b11, b12; b21, b22], then AB = [a11*b11 + a12*b21, a11*b12 + a12*b22; a21*b11 + a22*b21, a21*b12 + a22*b22]
Identity Matrix: I = [1, 0; 0, 1], condition for inverse is A * B = B * A = I

Theorems

A matrix A is the inverse of matrix B if and only if their product results in the identity matrix.
