# Is y=|sinx| a sinusoidal function?

Jul 10, 2016

Non-oscillatory, and so, not sinusoidal.

#### Explanation:

$y \ge 0 \mathmr{and} y \in \left[0 , 1\right] .$

There is no waveform in the graph of $y = | \sin x |$.

It is repeat arch-form, with period $\pi$.

The period of sinusoidal waveform y = sin x is #2pi
