Expert Answer:
Perpendicular Components Method
This method is usually used in the Cartesian plane, but can be used for other vectors too.

 In order to resolve a force into components, you will need to know the angle that it makes with the horizontal, vertical, xaxis, or the yaxis. Once this angle is known, you can construct a rightangled triangle with the force as hypotenuse and the other two sides along the x and y axes. The lengths of the two other sides are the magnitudes of the components along those directions, and may be calculated using trigonometry. The side adjacent to the angle is xcos(angle), and the side opposite is xsin(angle), where x is the magnitude of the original force.
 If a component points to the left or downwards, it is given a negative sign ().
