求值 (cos10°+根号3sin10°)/cos50°
求值 (cos10°+根号3sin10°)/cos50°
求值 (cos10°+根号3sin10°)/cos50°
(cos10°+√3sin10°)/cos50°
=2(1/2*cos10°+√3/2sin10°)/cos50°
=2(cos60°*cos10°+sin60°*sin10°)/cos50°
=2cos50°/cos50°
=2
(cos10°+√3sin10°)/cos50
=2*(1/2cos10+√3/2sin10)/cos50
=2sin(30+10)/cos50
=2sin40/cos50
=2cos50/cos50
=2
求值:sin10°-根号3乘cos10°/cos40°
求值 (cos10°+根号3sin10°)/cos50°
求值：1/sin10°-根号3/cos10°=
求值 1/sin10°-根号3/cos10°
化简sin10°-根号3*cos10°
化简求值 tan70°cos10°+根号3sin10°tan70°-2cos40°
求值cos10°/tan20°+根号3sin10°tan70°-2cos40°
求值：tan70°cos10°+根号下3*sin10°tan70°—2cos40°
求值；1/sin10°-√3/cos10°.
求值.1/sin10°-√3/cos10°
求值,根号下1-2sin10°cos10°/cos10°-根号下1-sin^2100°
(2cos70°+根号3sin10°)/cos10°
sin10°-根号3cos10°/cos40°
求(sin10°-根号3cos10°)/sin50°
化简1／sin10°-根号3／cos10°
化简：1/(sin10°) —根号3/cos10°
1/sin10°-根号3/cos10°=
1/sin10°减去根号3/cos10°,求过程.
