Problem

Let f(x)=∫sin⁡xcos⁡xet+sin⁡−1(t)2 dtf(x)=\int_{\sin x}^{\cos x}e^{t+\sin^{-1}(t)^2}\,dt on [0,π2]\left[0,\frac{\pi}{2}\right]. Then (1) f′′(c)=0f''(c)=0 for all c∈(0,π2)c\in\left(0,\frac{\pi}{2}\right) (2) f′′(c)=0f''(c)=0 for some c∈(0,π2)c\in\left(0,\frac{\pi}{2}\right) (3) f′(c)=0f'(c)=0 for some c∈(0,π2)c\in\left(0,\frac{\pi}{2}\right) (4) f(c)≠0f(c)\ne0 for all c∈(0,π2)c\in\left(0,\frac{\pi}{2}\right)
