x and y components of a vector

Consider a right triangle of hypotenuse AC and sides AB and BC. cos α = adj/hyp = AB/AC , then AB = AC cos θ sin α = opp/hyp = BC/AC , then BC = AC sin α. Similarly: AB = AC sin β and BC = AC cos β. We are interested in the projection of a force F lying in xy plane onto the x-axis and the y-axis. For a force F lying in xy plane: F = Fx i + Fy j , where Fx is the component of F along the x-axis and Fy is its component along the y–axis. Fx and Fy are algebraic quantities.
