y= sin x/2, 0 less than equal to x less than equal to 4pi... the question says state the amplitude and period for each equation and graph it over the indicated interval

Answer 1

since period of sin(x) is 2pi, period of sin(x/2) is such that 0 <= x/2 <= 2pi, or 0 <= x <= 4pi

amplitude is unchanged from sin(x)
