Resolving a vector into x and y components

An example figure from the Vector Diagram Generator.

On a grid with x and y axes, vector A at θ above the x axis, with its dashed components A_x along the x axis and A_y up to A’s tip — One vector A, 5 squares long at 37° above the horizontal, drawn from where the x and y axes cross, on a grid. Its angle is marked θ from the x axis, and its components A_x along the horizontal and A_y up to its tip are drawn as thinner dashed arrows.
