- where h is the hypotenuse. Once the components
- for each vector have been found, adding the
- respective components yields the components for
- the resultant vector. Finding the actual resultant
- vector is also based in the trigonometric definitions.
- Since the ratio of y/x is the definition of tangent,
- this ratio in turn yields the angle.
