设z=arctan(xy),y=e^x,求dz/dx.设z=arctan(xy),y=e^x,求dz/dx.设z=arctan(xy),y=e^x,求dz/dx.z=arctan(xy),y=e^x则
设z=arctan(xy),y=e^x ,求dz/dx .
设z=arctan(xy),y=e^x ,求dz/dx .
设z=arctan(xy),y=e^x ,求dz/dx .
z=arctan(xy),y=e^x
则
z=arctan(xe^x)
dz/dx
=(xe^x)'/(1+x^2*e^2x)
=(xe^x+e^x)/(1+x^2*e^2x)
dz/dx =1/(1+(xy)²) * (xy)'
=(y+xy') / (1+(xy)²)
=(1+x)e^x / (1+(xe^x)²)
设z=arctan(xy),y=e^x ,求dz/dx .
全导数:设z=arctan(xy),而y=e*x次方,求dz/dx设z=arctan(xy),而y=e*x次方,求dz/dx,
设z=arctan(xy)+2x^2+y^2,求dz

求Z=arctan(xy),而y=e^x的全导数
z=arctan【(x+y)/(1-xy)】的偏导数
讨论函数z=arctan(x+y)/(1-xy)的连续性方程是z=arctan[(x+y)/(1-xy)]
设函数z=(x^2+y^2)*{e^-arctan(x/y)},求dz与a^2z/axay

设z=f(x^2-y^2,e^(xy)),求偏导z/x,偏导z/y
设z=arctan(xy),y=e的x次方,求dz/dx不是dz/dx=@z/@y *dy/dx吗(@指偏导),为什么直接对z求导呢?那之后的dy/dx怎么求呢?
设z=(x+2y)e^xy,求dz
Z=arctan(xy) 而y=e的x次方,则dz/dx=?最好说下过程
设z=arctan(x+y),则σz/σy=?
