Web`x = +-(2pi)/3 + 2pik`, where k is an integer. Two of the above values belong to the interval `[0, 2pi]` when k = 0, `x = 2pi/3` and when k = 1, `x = 2pi-(2pi)/3 = (4pi)/3`. Webx = 0 is a root of f ( x) already. Since f ( x) is an odd function, it suffices to find only positive roots, because if r < 0 is a root, then f ( − r) = − f ( r) = 0 as well and − r > 0. Now if a positive root existed, let's say r > 0, then according to Rolle's theorem, f ′ …

For the IVT, there exist a z ∈ ( 0, π 2) such that h ( z) = 0. You could also use h ( 1) = cos ( 1) − 1 < 1 − 1 = 0 to get the argument working on the smaller interval.
