inflection point: $\left(\frac{\pi}{2}, 1\right)$


B)
local minimum: $(1.444,-0.246)$
local maximum: $(0.126,1.031)$
inflection points: $(0.785,0.393) ,(2.356,1.178$



C) C) no local extrema
inflection point: $\left(\frac{\pi}{2}, \frac{\pi}{2}\right)$


D) local minimum: $\left(\frac{5 \pi}{12}, \frac{5 \pi-6 \sqrt{3}}{12}\right)$
