根号3sin(-1200°)tan11π/6-cos585°tan(-37π/4)
根号3sin(-1200°)tan11π/6-cos585°tan(-37π/4)
根号3sin(-1200°)tan11π/6-cos585°tan(-37π/4)
√3sin(-1200°)tan11π/6 - cos585°tan(-37π/4)
=√3sin60°tanπ/6 -cos45°tanπ/4
=√3/2 -√2/2
=(√3 -√2)/2
根号3sin(-1200°)tan11π/6-cos585°tan(-37π/4)
化简√3sin(-1200°)tan11π/6-cos585°tan(-37π/4)=
√(3)sin(-1200°)tan11/6π-cos585°tan(-37/4π)
计算√3sin(-1200 度)/tan11π/3-cos585 度×tan(-37π/4)
