Important Formulas of Vector Algebra

1. Vector Representation:

$\mathbf{A} = \langle A_1, A_2, A_3 \rangle$

2. Position Vector:

$\mathbf{r} = \langle x, y, z \rangle = x\mathbf{i} + y\mathbf{j} + z\mathbf{k}$

3. Vector Addition:

$\mathbf{A} + \mathbf{B} = \langle A_1 + B_1, A_2 + B_2, A_3 + B_3 \rangle$

4. Scalar Multiplication:

$k \cdot \mathbf{A} = \langle kA_1, kA_2, kA_3 \rangle$

5. Dot Product:

$\mathbf{A} \cdot \mathbf{B} = A_1B_1 + A_2B_2 + A_3B_3$

6. Cross Product:

$\mathbf{A} \times \mathbf{B} = \langle A_2B_3 - A_3B_2, A_3B_1 - A_1B_3, A_1B_2 - A_2B_1 \rangle$

7. Scalar Triple Product:

$\mathbf{A} \cdot (\mathbf{B} \times \mathbf{C}) = \mathbf{B} \cdot (\mathbf{C} \times \mathbf{A}) = \mathbf{C} \cdot (\mathbf{A} \times \mathbf{B})$

8. Vector Triple Product:

$\mathbf{A} \times (\mathbf{B} \times \mathbf{C}) = (\mathbf{A} \cdot \mathbf{C}) \cdot \mathbf{B} - (\mathbf{A} \cdot \mathbf{B}) \cdot \mathbf{C}$

9. Unit Vector:

$\hat{\mathbf{A}} = \dfrac{\mathbf{A}}{\|\mathbf{A}\|}$

10. Projection of $\mathbf{A}$ onto $\mathbf{B}$:

$\text{proj}_{\mathbf{B}} \mathbf{A} = \dfrac{\mathbf{A} \cdot \mathbf{B}}{\|\mathbf{B}\|} \cdot \dfrac{\mathbf{B}}{\|\mathbf{B}\|}$
