=(sina-sina-tana)/(-sina+sina+tana)=-1
cosαcos[(2k+1)π]-sinαsin[(2k+1)π]为什么等于-cosα
求证(1-cosα)/sinα=sinα/(1+cosα)=tan(α/2)(α≠kπ,k∈z) 快回答!
若α∈(-π/2+2kπ,2kπ)(k∈Z),则sinα,cosα,tanα的大小关系是A.tanα>sinα>cosαB.tanα>cosα>sinαC.tanα<sinα<cosαD.tanα<cosα<sinα
2(sin a)^2+(2sin a*cos a)/(1+tan a)=k试用k表示sin a-cos aa∈(π/4,π/2)
已知sin(α-3π)+cos(π/2+α)=m,求cos(α-7π/2)+2sin(2kπ-α)的值
sin(kπ-α)*cos〔(k-1)π-α〕/sin〔(k+1)π+α〕*cos(kπ+α) ,k属于Z
[sinπ(/2+α)-cos(3π/2-α)]/[tan(2kπ -α)+cot(-kπ+α)]=[sin(4kπ-α)sin(π/2 -α)]/[cos(5π+α)-cos(π/2+α)
化简:sin(kπ-2)cos[(k-1)π-2]/sin[(k+1)π+2]cos(kπ+2),k属于Z
已知sin(θ+kπ)=2cos[θ+(k+1)π],k∈Ζ,求4sinθ-2cosθ/5cosθ+3sinθ的值
①利用公式sin(π-θ)=sinθ和sin(∏+θ)=-sinθ证明:sin(-θ)=-sinθ②证明tanθsinθ∕tanθ-sinθ=1+cosθ∕sinθ③已知sinα-2cosα+1=0,α≠kπ+π∕2,k∈z求:tan(3π-α)和1∕sin2α-sinαcosα+1的值
当2kπ-π/4≤α≤2kπ+π/4(k∈Z),化简√(1-2sinα×cosα)+√(1+2sinα×cosα)
cos(α+k·2π)= sin(α+k·2π)= tan(α+k·2π)= sin(-α)= cos(-α)= tan(-α)=要和书上的一样.
当k为任意整数时,化简 cos(2kπ-x)(-sin(2kπ-x))
sin kπ/4(k从1到n)的和为什么等于{cos[π/8]-cos[(n+1/2)π/4]}/2sin(π/8)?
函数y=sinα+cosα-4sinαcosα+1,且2sin^2α+sin2α/1+tanα=k,π/4
求证sin(π/2 +α)-cos(3π/2 -α)/tan(2kπ -α)+cot(-kπ+α)=sin(4kπ -α)sin(π/2 -α)/cos(5π+α)sin(π/2 +α)-cos(3π/2 -α)/tan(2kπ -α)+cot(-kπ+α)=sin(4kπ -α)sin(π/2 -α)/cos(5π+α)-cos(π/2 + α)谁帮我做做
化简:cos[(k+1)π-α]*sin(kπ-α)/cos(kπ+α)*sin[(k+1)π+α]拜托了各位
化简[sin(kπ-α)*cos(kπ+α)]/{sin[(k+1)π+α]*cos[(k+1)π-α]}
