Question

把下列角度化成弧度~（1）22°3′（2）-210°（3）1200°要答案和过程~~谢谢了

Answer 1

(1)22°3′
=(22+3/60)°
=22.05°
=22.05*PI/180
=0.384845弧度

(2)-210°
=-210*PI/180
=-3.665191弧度

(3)1200°
=1200*PI/180
=20.943915弧度
=20.943915-4*(2*PI)
=2.094395弧度

Answer 2

(1)22°3′ =(22+3/60)° =22.05° =22.05*π/180
=0.384845π
(2)-210° =-210*π/180
=-3.665191π
(3)1200° =1200*π/180 =20.943915π =20.943915-4*(2*π)
=2.094395π
