Questions: (a) The sine and cosine curves y=a sin (k x) and y=a cos (k x), k>0 have amplitude and period. The sine curve y=5 sin (2 x) has amplitude, period π, an appropriate interval to graph one period is (0, ). (b) Graph one period of y=5 sin (2 x) and label the x-coordinates of the key points used for graphing the function.

Transcript text: (a) The sine and cosine curves $y=a \sin (k x)$ and $y=a \cos (k x), k>0$ have amplitude $\square$ and period $\square$ - The sine curve $y=5 \sin (2 x)$ has amplitude $\square$ period $\pi$ an appropriate interval to graph one period is $(0$, $\square$ ). (b) Graph one period of $y=5 \sin (2 x)$ and label the $x$-coordinates of the key points used for graphing the function.
