Applications of Circular Functions
- A sinusoidal function has a rule of the form y=a\sin (nt+k)+c, or, equivalently, of the form y=a\cos (nt+k)+c. Such functions can be used to model periodic motion.
- There are plenty of examples of periodic motions. For instance, the periodic switch between daytime and night time, circular motions of pendulum, yo-yo, and more.
