Most Important Formulas of Matrices and Determinants

Matrices

1. Addition and Subtraction:

$(A + B)_{ij} = A_{ij} + B_{ij}$

$(A - B)_{ij} = A_{ij} - B_{ij}$


2. Scalar Multiplication:

$(cA)_{ij} = c \cdot A_{ij}$


3. Matrix Multiplication:

$(AB)_{ij} = \sum_{k=1}^{n} A_{ik} \cdot B_{kj}$


4. Identity Matrix:

$I_n = \begin{bmatrix} 1 & 0 & \cdots & 0 \\ 0 & 1 & \cdots & 0 \\ \vdots & \vdots & \ddots & \vdots \\ 0 & 0 & \cdots & 1 \end{bmatrix}$


5. Transpose:

$(A^T)_{ij} = A_{ji}$


6. Symmetric Matrix:

$A = A^T$


Determinants

1. 2x2 Matrix:

$\text{det}\left(\begin{bmatrix} a & b \\ c & d \end{bmatrix}\right) = ad - bc$


2. 3x3 Matrix:

$\text{det}\left(\begin{bmatrix} a & b & c \\ d & e & f \\ g & h & i \end{bmatrix}\right) = a(ei - fh) - b(di - fg) + c(dh - eg)$


3. Properties of Determinants:

  • $\text{det}(cA) = c^n \cdot \text{det}(A) \quad (\text{for an } n \times n \text{ matrix } A \text{ and a scalar } c)$

  • $\text{det}(A^T) = \text{det}(A)$

  • $\text{det}(AB) = \text{det}(A) \cdot \text{det}(B)$


4. Cramer's Rule for Solving Linear Equations:

If Ax=B is a system of linear equations, and A is invertible, then the solution is given by:

$x_i = \frac{\text{det}(A_i)}{\text{det}(A)}$
