How can a force be resolved in to rectangular components?

A force can be resolved into rectangular components by identifying its horizontal and vertical components. This can be done using trigonometry, specifically sine and cosine functions. The horizontal component is found by multiplying the magnitude of the force by the cosine of the angle it makes with the horizontal axis, and the vertical component is found by multiplying the magnitude of the force by the sine of the angle.
