A vector is a
quantity that has both magnitude and direction and to identify the components
of vector, you need to break it into parts called components. These components depict
the influence of that vector in a given direction. For example, in the vector
(6, 2), the horizontal or x-axis component is 6 and the vertical or y-axis
component is 2. With this, you have an angle and a magnitude to define a
vector, where you have to find the components yourself with the help of
trigonometry. The magnitude of vector is expressed as v and by multiplying both
sides of these equations by v, you can expressed the x and y components as Vx = vcos and Vy = vsin.
The combined
influence of the two components is equivalent to the influence of the single
two-dimensional vector and this single two-dimensional vector could be replaced
by the two components.
