3. Вычислите: $\frac{3}{\pi} (arcsin(-\frac{\sqrt{3}}{2}) + arctg 1)$.

$\frac{3}{\pi} (arcsin(-\frac{\sqrt{3}}{2}) + arctg 1)$ $arcsin(-\frac{\sqrt{3}}{2}) = -\frac{\pi}{3}$ $arctg 1 = \frac{\pi}{4}$ $\frac{3}{\pi} (-\frac{\pi}{3} + \frac{\pi}{4}) = \frac{3}{\pi} (\frac{-\pi}{12}) = -\frac{3\pi}{12\pi} = -\frac{1}{4}$ Ответ: -$\frac{1}{4}$
