化简f(X)=(1-√2sin（2X－π／4）)／cosX

化简f(X)=(1-√2sin（2X－π／4）)／cosX 化简f(X)=(1-√2sin（2X－π／4）)／cosX 化简f(x)=(1-√2*cos(2x-π/4))/sin(π/2-x) 化简f(x)=(1+√2*cos(2x-π/4))/sin(π/2-x) f(x)=(√2 sin x + cos x)/(sin x +√(1- sin x)) (x∈ [0,π] 的最大值? 三角函数公式转化问题f(x)=2√3 sin(x/3)cos(x/3)－2[sin(x/3)]^2 是怎么转化成f(x)=2sin(2x/3 + π/6)－1 f(x)=（1+cotx)sin^2x-2sin(x+π/4)sin(x-π/4)还有一题, 已知函数f(x)=(1+1 anx)sin^2x+m sin(x+π/4)sin(x-π/4) f(x)=2sinx*sin(x+π/3) 化简 f(x)=sin^2x+sinxcosx-1/2,化简 f(x)=(1+1/tanx)sin(x)^2化简 化简f(x)=(1+cos2x)sin^2x f(x)=sin(πx^2)(-1 若f(x)=sin πx/6,则f(1)+f(2)+...+f(102)=? 若f(x)=sin(π/4)x,求f(1)+f(2)+.+f(2010) 函数f(x)=2sin(π/4-x)×cos(π/4+x)-1化简 f(sin 2/x )=1+cosx 求f(x) 已知函数 f(x)=sin^2(πx/4)-√3sin(πx/4)·cos(πx/4) (1)求f(x)最大值及此时x值 (2)求f(1)+f(2)+f(3)+已知函数 f(x)=sin^2(πx/4)-√3sin(πx/4)·cos(πx/4)(1)求f(x)最大值及此时x值(2)求f(1)+f(2)+f(3)+...+f(2010)值
