Direction Cosines
Direction cosines provide information about the angle between a vector and the positive x-axis. They are calculated using the following formula:
where:
a is the magnitude of the vector a
b is the magnitude of the vector b
c is the magnitude of the vector c
Direction Ratios
Direction ratios are another way to express the angle between a vector and the positive x-axis. They are calculated using the following formula:
where:
a is the magnitude of the vector a
b is the magnitude of the vector b
Examples
which means that the angle between the vectors is 60 degrees.
which means that the angle between the vectors is 37 degrees
