SINE

Examine the course of the sine function. Set the belt speed by using the buttons. Carefully tune the amplitude.

Difference between graphs $\sin x$ , $\sin \frac{x}{2}$ and $\sin 2x$

Difference between graphs $\sin x$ , $2\sin x$ a $\frac{1}{2}\sin x$

What would a $2\sin \frac{x}{2}$ graph look like?
Cosine graph looks the same as the sine graph, but moved by an interval of $\frac{\pi}{2}$ .
