Correspondence between geometrical and differential definitions of the sine and cosine functions and connection with kinematics

, 2011
In classical physics, the familiar sine and cosine functions appear in two forms: (1) geometrical, in the treatment of vectors such as forces and velocities, and (2) differential, as solutions of oscillation and wave equations. These two forms correspond
