Answer» Show that the function given by $f (x) = s i n x$ is strictly increasing in $(0, \frac{π}{2})$ strictly decreasing in $(\frac{π}{2}, π)$ neither increasing nor decreasing in $(0, π)$

Show that the function given by f(x)=sin x is strictly increasing in (0,π2) strictly decreasing in (π2,π) neither increasing nor decreasing in (0,π)

Answer»

Show that the function given by $f (x) = s i n x$ is
strictly increasing in $(0, \frac{π}{2})$

strictly decreasing in $(\frac{π}{2}, π)$

neither increasing nor decreasing in $(0, π)$
