Figure 2.6: Resolution of a vector using Parallelogram Method
The trigonometric method of vector resolution involves using trigonometric functions to determine
the components of the vector. Beside that there is two law which can be used to determine the
component at any axis and it is law of cosines and law of sines.
Figure 2.7: The Trigonometric Method
The law of cosines for calculating one side of a triangle when the angle opposite and the other two
sides are known. Can be used in conjunction with the law of sines to find all sides and angles.
