y=x^2(√x-sin2x),求dy

y=x^2(√x-sin2x),求dy y=e^x/x^2+sin2x 求dy/dx y=3x+sin2x求dy, 设y=sin2x/(1+x^2),求dy/dx, 设y=sin2x/(1+x^2),求dy/dx, 设y=e∧1/x+sin2x,求dy 设y=x分子sin2x.求dx分子dy. 、已知y= (e^-x )sin2x,求dy y=x*sin2x则,dy=? 求函数y=(x^2+3x)^sin2x的导数dy/dx y=x^2-sin2x,则dy/dx 求函数y=3sin2x+4e^x的导数dy/dx ,微分dy 设y＝sin2x＋√〔1+2x〕+e³,求dy/dx y=sin2x,求dy 设y＝sin2x/x的平方 求dy y=x^2x,求dy 设y=(sin2x)^x,求dy/dx最好过程能具体点啦 设y=e的x分之1次方+sin2x,求dy
