, Why do we want to know
bearing?
Imagine you have to describe the location of a point,
somewhere on a map?
Location can be described in 2 ways:
i. The coordinates, in terms of latitude and longitude
ii. The location of a place, relative to another location (the distance and direction to
the location)
Let us use point X as in example, how could you tell someone where it is
without a GPS?
For example, I am at point X, how would you be able to find me?
X
