๐Ÿ”น Basic Vector Formulas


1. Vector Representation:




2. Magnitude of Vector:



3. Unit Vector:



4. Addition of Vectors (Resultant):


 (when angle ฮธ between A and B is known)



5. Subtraction of Vectors:


---


๐Ÿ”น Types of Products


1. Dot Product (Scalar Product):


Result → Scalar


2. Cross Product (Vector Product):


Result → Vector (direction given by right-hand rule)
