求值:1/sin50°+√3/cos50°
求值:1/sin50°+√3/cos50°
求值:1/sin50°+√3/cos50°
1/sin50°+√3/cos50°
=(cos50+√3sin50)/(sin50 cos50)
=2(1/2cos50+ √3/2sin50)/(1/2(sin100))
=4(sin(50+30)/sin100
=4sin80/sin100
=4
求值:1/sin50°+√3/cos50°
求值:1/sin50°+根号3/cos50°
√(cos50°-sin50°)²+|cos50°-1|
求值:2sin50°+cos10°(1+根号3tan10°)/根号下1+2sin50°cos50°
求职:1/sin50° +√3/cos50°
求1/sin50°+√3/cos50°的值
1 / sin50 + √3 / cos50 =
求值sin70°cos50°+sin20°sin50°=?
1/sin50°+根号下3/cos50°=
化简 1/sin50°+根号下3/cos50°
1/sin50+根号3/cos50谢
求值:2sin50°+cos10°*(1+根号3tan10°)/cs35°cos40°+cos50°cos55°是cos35° 不好意思。打错了
求值sin50°(1+√3tan10°)
√2(cos50°-sin50°).化简
sin50°*cos50°=1/2sin100°
求1/sin50度+根号3/cos50度
求1/sin50'+根号下3/cos50'的值?
化简 求值cos50°( tan10°-√3)
