已知Y=sin^4*3xcos^3* 4x求Y的导数

已知Y=sin^4*3xcos^3* 4x求Y的导数 已知tanx=-3/4,求2sin^2 x+3sin xcos x-cos^2 x 已知函数f(x)=sin xcos x+sin x/cos x+3,若f(lg a)=4,则f(lg 1/a)的值为________. 数学题目已知函数f(x)=+2sinωxcosωx+2f（a）=2/3求sin(5/6π-4a) y=1-4sin²xcos²x的导数y'= ∫sin^3 xcos xdx. sin^4x-sin^2xcos^2x+cos^4x =(sin^2x+cos^2x)^2-3sin^2xcos^2x 那么这个依据呢?老师 (1-(sin^4x-sin^2xcos^2x+cos^4x)/sin^2x +3sin^2x 化简[1-(sin^4 x-sin^2 xcos^2 x+cos^4 x)]/(sin^2 x)+3sin^2 x 已知tan (π+ α)=-2/1,求下列各式的值(1)[2cos(π-α)-3sin(π+α)]/[4cos(α-2π)+sin(4π-α)](2)sin(α-2π)xcos(α+5π) 求函数y=2sin xcos x+2sin x+2cos x+4的值域 求函数y=sin平方X+2sin xcos x+3cos平方的最大值和最小值 已知函数f（x）=sin^π/4x-√3sinπ/4xcosπ/4x 1.求f x的最大值及此时X的值 2.求F(1)+F(2)+F(3)+..+F(201 化简:sin(n∏-2/3∏)Xcos(n∏+4/3∏),n∈Z. 求定积分∫(1/sin^2xcos^2x)dx上标派/3下标派/4 SIN^4XCOS^4XD的不定积分 1/(sin^4 xcos^4 x)积分 sin^2xcos^3x的不定积分,
