Answer
Increasing on:$\qquad (0, \displaystyle \frac{\pi}{2}), (\displaystyle \frac{7\pi}{6}, \frac{3\pi}{2}), (\displaystyle \frac{11\pi}{6}, 2\pi)$
Decreasing on: $\displaystyle \qquad(\frac{\pi}{2}, \frac{7\pi}{6}), (\displaystyle \frac{3\pi}{2}, \frac{11\pi}{6})$
Work Step by Step
$f(x)=\sin^{2}x+\sin x, \qquad 0$
