Direction of Resultant Vector
### Formula:
$$\tan\phi = \frac{B\sin\theta}{A+B\cos\theta}$$
### Terminologies:
- φ → Angle made by resultant vector with the first vector.
- A → Magnitude of first vector.
- B → Magnitude of second vector.
- θ → Angle between the two vectors.
- tanφ → Trigonometric ratio used to find direction.
### Usage:
- Used to determine the direction of resultant vector.
