               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.
