\[\boxed{\mathbf{997}\mathbf{.}}\]
\[y = 2\sin{5x} + 3\cos\frac{x}{2}\]
\[x = \frac{\pi}{3}:\]
\[0 = 6 \bullet \sin\frac{\pi}{6} - \frac{2}{5} \bullet \cos\frac{5\pi}{3} + C\]
\[0 = 6 \bullet \frac{1}{2} - \frac{2}{5} \bullet \frac{1}{2} + C\]
\[0 = 3 - 0,2 + C\]
\[C = - 2,8.\]
\[Ответ:\ \ \]
\[F(x) = 6\sin\frac{x}{2} - \frac{2}{5}\cos{5x} - 2,8.\]
