A force vector has a magnitude of 576 newtons and points at an angle 43o of below the positive x axis. What are (a) the x scalar component and (b) the y scalar component of the vector?

This is a matter of resolving a vector into components. Basic stuff.
a) 576 cos 43
b) 576 sin (43)
assuming the +x axis is up.
