Quizplus · Accepted Answer

The amplitude of a sine function, such as $y = \sin \frac{1}{3}x$, is the coefficient in front of the sine function. Since there is no coefficient explicitly written, it is understood to be 1, which is the standard amplitude for sine and cosine functions. The fraction $\frac{1}{3}$ affects the period, not the amplitude.
