Amplitude is the height from the mean, or rest, value of the function to its maximum or minimum. The period is the distance required for the function to complete one full cycle. For the sine function, the amplitude is given by and the period is defined as. The same is true for a cosine function.
Due to this similarity, any cosine function can be written in terms of a sine function as cos x=sin (x+ Ï/2). There is also no difference in the frequency of a cosine and its corresponding sine wave. Both have a maximum of 1 and a minimum of -1. Sine function curve stats at 0 and then moves upward to 1 by Ï/2 radians and then comes back to -1.
