WebNov 18, 2016 · 4 Answers. Consider h ( x) = cos ( x) − x. Then, h ( 0) = 1 and h ( π 2) = − π 2. Hence, h ( 0) > h ( π 2) and, clearly, h ( x) is continuous. 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.
