f(x)=sin(x)(sin(2x))

Solution

f (x) = sin (x) (sin (2 x))

Solution

Period : 2 π

Domain : - \infty < x < \infty

Range : - \frac{4}{3 3} \leq f (x) \leq \frac{4}{3 3}

X Intercepts : (2 πn, 0), (π + 2 πn, 0), (\frac{π}{2} + 2 πn, 0), (\frac{3 π}{2} + 2 πn, 0), Y Intercepts : (0, 0)

Asymptotes : None

Extreme Points : Minimum (2 πn, 0), Maximum (arccos (\frac{1}{3}) + 2 πn, \frac{4}{3 3}), Minimum (arccos (- \frac{1}{3}) + 2 πn, - \frac{4}{3 3}), Maximum (π + 2 πn, 0), Minimum (- arccos (- \frac{1}{3}) + 2 π + 2 πn, - \frac{2}{3} sin (2 (- arccos (- \frac{1}{3}) + 2 π))), Maximum (2 π - arccos (\frac{1}{3}) + 2 πn, - \frac{2}{3} sin (2 (2 π - arccos (\frac{1}{3}))))
