![\bf sin^2(x)+cos(x)\iff [sin(x)]^2+cos(x)\\\\ -----------------------------\\\\ \cfrac{dy}{dx}=2sin(x)cos(x)-sin(x)\implies 0=2sin(x)cos(x)-sin(x) \\\\\\ 0=sin(x)[2cos(x)-1]\implies \begin{cases} 0=sin(x)\\ sin^{-1}(0)=\measuredangle x\\ \pi \\ ----------\\ 0=2cos(x)-1\\\\ \frac{1}{2}=cos(x)\\\\ cos^{-1}\left( \frac{1}{2} \right)=\measuredangle x\\\\ \frac{\pi }{3},\frac{5\pi }{3} \end{cases}](/tpl/images/0457/3974/f098c.png)
