The amplitude of a sine or cosine function is found as a multiplier "a" in the form: y = #a*sin(b(x-c))+d#. Since this function does not have a multiplier other than 1, then the amplitude is 1.

Explanation:

The period of a sine or cosine function is calculated by using #(2pi)/b# or #360^o/b# depending on whether you wish to respond in radians, or degrees. This equation has #pi# as a multiplier on the angle, x, making the period equal to 2.
