(cosθ+sinθ)=√2sin(θ+π/4)
(cosθ+sinθ)=√2sin(θ+π/4)
(cosθ+sinθ)=√2sin(θ+π/4)
(cosθ+sinθ)=√2sin(θ+π/4)
求证sinθ-cosθ+1/sinθ+cosθ-1=1+sinθ/cosθ
求证:(1+cosθ+cosθ/2) /(sinθ+sinθ/2)=sinθ/1-cosθ
化简:1+sinθ+cosθ+2sinθcosθ /1+sinθ+cosθ
若sin θ+cos θ/sin θ-cos θ=2,则sin θcos θ的值是请问如何判断sin θcos θ的正负
求证(1-sinθcosθ)除以(cos^2θ-sin^2θ)=(cos^2θ-sin^2θ)除以(1+2sinθcosθ)
sin^2θ-3sinθcosθ+1
参数方程化为普通方程 x=(sinθ+cosθ)/(2sinθ+3cosθ) y=sinθ/(2sinθ+3cosθ)
化简2cosθ/√1-sin^2θ+√1-cos^2θ/sinθ
若а,θ为锐角,且tanθ=(sinа-cosа)/(sinа+cosа),求证:sinа-cosа=√2sinθ
化简【1+sinθ-cosθ/1+sinθ+cosθ】+cot(θ/2)
求证sinθ/(1+cosθ)+(1+cosθ)/sinθ=2/sinθ
(1+sinθ+cosθ)/(sin θ/2+cosθ/2)
已知sinθ+cosθ=m,求sin^3θ+cos^3θ的值
已知sinθ-cosθ=1/2,且θ为锐角,则sinθ+cosθ=
求值:(tan10°-√3)×cos10°/sin50° 求证:[sin(2α+β)]/sinα- 2cos(α+β)=sinβ/cosα 化简cosθ+cos(θ+2π/3)+cos(θ+4π/3) 证明:sin(α+β)sin(α-β)=sin^2α-sin^2β
化简 1.(sinα+cosα)的平方 2.cos*4θ-sin*4θ
2sinθ = cosθ + 1,怎么求sin
