Question

On a separate diagram, sketch each of the following graphs for the given interval, stating the amplitude, the period and the range of values of $y$ corresponding to the interval. $y = \frac{1}{2} \cos 3x$, $-360^\circ \le x \le 0^\circ$ $y = 5 \cos \pi x$, $0 \le x \le 6$

Accepted Answer

(i) amplitude $\dfrac{1}{2}$, period $120^\circ$, range $-\dfrac{1}{2} \le y \le \dfrac{1}{2}$; (ii) amplitude $5$, period $2$, range $-5 \le y \le 5$
