z=e^xsiny,x=cosy,求dz/dy,
z=e^xsiny,x=cosy,求dz/dy,
z=e^xsiny,x=cosy,求dz/dy,
Z=e^sinycosy=e^(1/2sin2y)
dz/dy=[e^(1/2sin2y)]'=e^(1/2sin2y) * (1/2sin2y)'=e^(1/2sin2y) * cos2y
z=e^xsiny,x=cosy,求dz/dy,
z=(e^3y) +(x^2)Xsiny,求dz
其实我是想问这个,z=e^x*siny,x=cosy,求dz/dy.求帮助呀~
z=(y^2-x^2)/(y^2+x^2)的二阶偏导数,还有这个也是Z=(cosy+xsiny)e ^x,过程要相信点的,
z=xsiny,dz=? 在线等答案,求详细过程,谢谢.
∫e^x[(1-cosy)dx-(y-siny)dy],其中c为区域 0≤x≤π,0≤y≤sinx的边界曲线取正向.求曲线积分P(x,y)=e^x(1-cosy) -对y求偏导数=e^xsinyQ(x,y)=e^x(siny-y) -->对x求偏导数=e^xsiny-ye^xI=∫∫(e^xsiny-ye^x-e^xsiny)dxdy=-∫∫(ye
