Q: in the range of 0 ° to 360 ° (i.e. 0 ° ≤ α< 360 °), find the same angle as the end edge of the following angles. 1) - 312 ° 2) 478 ° 3) 653 ° 4) - 67 After solving the above, if you have leisure, then solve the following What is K in β = k × 360 ° + α? What is log? The angle opposite an arc with a long radius is called an angle of 1 radian. The system of measuring angles in radians is called radian system-
