When a vector is represented as a line segment, the starting point is called as the Initial Point of a Vector.
The components and the magnitudes of a vector can be found out with the help of initial point of a vector..

In the above figure, PQ is a vector and P the initial point of the vector.

A. (3, 4)
B. (4, 5)
C. (3, 5)
D. None of these
Correct Answer: A
Step 1: In figure, A is the initial point of a vector AB.
Step 2: The value of A is (3, 4). [Given.]
Step 3: So, the value of the initial point of a vector is (3, 4).
Q1: What is the initial point of vector AB if A = (3, 4) and B = (7, 8)?
Q: How do you find the initial point of a vector?
A: If given a visual representation, identify the starting point of the vector. If given coordinates, the initial point will be explicitly stated or can be derived based on the vector's components and terminal point.
