Ответ:
Переводим градусы в радианы по формуле: \(\alpha^\circ=\alpha\cdot\frac{\pi}{180}\).
1.1. \(10^\circ=10\cdot\frac{\pi}{180}=\frac{\pi}{18}\); \(135^\circ=135\cdot\frac{\pi}{180}=\frac{3\pi}{4}\); \(-60^\circ=-60\cdot\frac{\pi}{180}=-\frac{\pi}{3}\).
1.2. \(18^\circ=18\cdot\frac{\pi}{180}=\frac{\pi}{10}\); \(150^\circ=150\cdot\frac{\pi}{180}=\frac{5\pi}{6}\); \(-90^\circ=-90\cdot\frac{\pi}{180}=-\frac{\pi}{2}\).
1.15. \(45^\circ=45\cdot\frac{\pi}{180}=\frac{\pi}{4}\); \(160^\circ=160\cdot\frac{\pi}{180}=\frac{8\pi}{9}\); \(-75^\circ=-75\cdot\frac{\pi}{180}=-\frac{5\pi}{12}\).
1.16. \(216^\circ=216\cdot\frac{\pi}{180}=\frac{6\pi}{5}\); \(15^\circ=15\cdot\frac{\pi}{180}=\frac{\pi}{12}\); \(-60^\circ=-60\cdot\frac{\pi}{180}=-\frac{\pi}{3}\).
