求(sin10°-根号3cos10°)/sin50°
化简sin10°-根号3*cos10°
求1/sin10°-根号3/cos10°的值.
化简:cos10°(tan10°-根号3)/sin50°
求值:(tan10°-根号3)cos10°÷sin50°
(2cos70°+根号3sin10°)/cos10°
(cos10°-根号3sin10°)/sin20°
化简:1/(sin10°) —根号3/cos10°
1/sin10°-根号3/cos10°=
化简1/sin10°-根号3/cos10°
求(tan10°-根号3)*cos10°/sin50°的值
求1/sin10°-根号3/cos10°的值(要过程)
