i don't see this in my book

in a coordinate system, a vector is oriented at angle theta with respect to the x-axis. The y component of the vector equals the vector equals the vector's magnitude multiplied by which trigonometric function?

With vectors, the horizontal component (the x) is the force A x cos theta.

The verticl component (the y) is the force A x sin theta.
