How are the components of a vector determined mathematically?

Answers

Answer:

In a two-dimensional coordinate system, any vector can be broken into x -component and y -component. For example, in the figure shown below, the vector →v is broken into two components, vx and vy . Let the angle between the vector and its x -component be θ .

Answer:

The components of a vector are determined using the coordinates of the initial and terminal points of the vector. The horizontal component is calculated by subtracting the x coordinate of the initial point from the x coordinate of the terminal point. The vertical component is calculated by subtracting the y coordinate of the initial point from the y coordinate of the terminal point.
