∫sin2x/sin^4x+cos^4xdx?
数学 积分sin^3x/cos^4xdx 积分cos^4x/sin^3xdx 请详细解答,谢谢!
不定积分∫(sin2x)/(sin²x)dx ∫sin³xcos²xdx
求函数fx=(sin^4x+cos^4x+sin^2x*cos^2x)/(2-sin2x)
求定积分(x³+sin²x)cos^4 xdx 范围为(-π/2,π/2)
函数f(x)=-√2(sin2x+π/4)+6 sin x cos x-2cos²x+1
已知cos(π/4-x)=-3/5,求sin2x/sin(x+π/4)
已知COS(π/4-X)=-4/5,求(SIN2X-2SIN^X)/(1+TANX)
已知cos(x+π/4)=3/5求sin2x-2sin^2x
两个个数学证明题1.证明:cos2x+sin2x=√2sin(sin2x+π/4)2.证明:αsinαx+cosαx=√
求函数f(x)=(sin^4x+cos^4x+sin^2cos^2x)/(2-sin2x)的最小正周期、最大值和最小值.
求函数Y=sin^4x +cos^4x +sin^2x cos^2x 除以2-sin2x的最小正周期,最大值最小值
1.y=cos^4x+sin^4x 求周期 2.y=(sin2x+sin(2x+π/3))/( cos2x+cos(2x
