Mathematics-Magnitude of a Vector
A Vector has both magnitude and direction. The length of the arrow shows its magnitude and arrowhead shows its direction.
Magnitude of a vector, a is calculated by using the formula | a |, the modulus of a vector a.
If a vector has magnitude 1, then it is called unit vector.
How to scale a vector ?
A vector can be scaled by Multiplying the vector with a scalar value.
Eg) Magnitude of a vector, a = |a| = √(52 + 42 ) , if vector a = 5i + 4j
