Find a true statement about the function \( f(x)=\sin x+\frac12\cos2x \) on the interval \( [0;\pi] \).
The function has global minima at the points \( x=0 \), \( x=\frac{\pi}2 \) and \( x=\pi \).
The only global minimum of \( f \) on this interval is at the point \( x=\frac{\pi}2 \).
The only global maximum of \( f \) on this interval is at the point \( x=\frac{\pi}6 \).
The function \( f \) has no global minimum on this interval.
