(Solved): Let \( \mathcal{F}(x) \) be an antiderivative of \( \cos 2 x \sin 5 x \). Evaluate \( \mathcal{F}( ...

Let \( \mathcal{F}(x) \) be an antiderivative of \( \cos 2 x \sin 5 x \). Evaluate \( \mathcal{F}(\pi)-\mathcal{F}(0) \). None of these \[ \begin{array}{l} \frac{5}{21} \\ \frac{2}{21} \\ \frac{10}{21} \\ -\frac{2}{21} \end{array} \]
