e^(-y^2)+cos(x^2)=0 求dy/dx是隐函数求导问题

y=cos^3(2x)+e^x求导数 y=cos^3(2x)+e^x求导 设y=cos(x^2+e^x)求dy 设y=e^cos^2*1/x,求dy 一阶线性微分方程y´+xsin2y=x【e^(-x^2)】【cos^2y】 y(0)=1 求y ) y=cos(x-y)求一阶导数y=cos(x-y)求三阶导数y=e^-xy=(e^2x)(sinx) 已知y=y(x)由方程cos(x+y)+e^(x-y)=2 y' y'|(x,y)=(0,0)已知y=y(x)由方程cos(x+y)+e^(x-y)=2所确定,求y' ,y'|(x,y)=(0,0) e^(-y^2)+cos(x^2)=0 求dy/dx是隐函数求导问题 计算y = e–2 x cos x ,求y ′ = 设函数y=e^2x+cos x求倒数y'与微分dy 急,函数y=f(x)由e的2x+y次方—cos(xy)=e-1表示,求y(0)的导数 y=cos^2(e^x),求dy.dy=dcos^2(e^x) 1=2cos(e^x)*dcos(e^x) 2=-2cos(e^x)sin(e^x)de^x 3=-(sin2e^x)e^x dx 4第二步为什么会这样变化,怎么多出了个2cos(e^x)? 1,y=e^tanxcos^3x,求dy 2,函数y=y（x）由方程e^(x+y)+arctan(xy)=0确定,求dy/dxy=e^tanx*cos^3x cos(y^2-x^2)求导u(x,y)=e^2xycos(y^2-x^2) 求微分 y=ln(1-x^2) y=e^-x +cos(3+x) y=sin2x 证明COS（X+Y）COS（X-Y）=COS^2X-SIN^2Y 证明cos(x+y)cos(x-y)= cos^2(x)-sin^2(y) 隐函数,y=e的x+y次幂怎么求导y=e^x+y x^3+y^3+cos(x+y)=0ln根号下x^2+y^2 -arctany/x=2xcosy=sin(x+y)cos(x^2y)=x这五道题怎么求导，都是高数中的隐函数求导。y'=y/1-yy'=3x^2-sin(x+y)/sin(x+y)-3y^2y'=y+x/x-yy'=cosy-cos(x+y)/cos
