求导y=(2+5x)^10)/xy=(2+5x)^10/x

x^2-y^2=xy 求导 求导y=(2+5x)^10)/xy=(2+5x)^10/x cos(xy^2)=x+2y求导 y=x^1/x求导 xy-2x+y-z-2=0求导 x^2+xy-y^2=4求导 x^2-XY+Y^2=9求导 x^2-xy-y^2=1 怎么求导 e^(xy)-2x-y=0.求导 y^2-2xy+10=0求导 f(x^2-y^2,x-y)=x+y+x^2-xy,求f'(x,y)对y求导 微分求导:3X^3+2XY^2-Y=5,求dY/dX. xy-sin(2x+3y)=5隐函数求导 隐函数求导x^2*y-6xy^3=-5RT 6x-√(2xy)+xy=y^2 怎麼求导啊? x^2+xy+y^2=4,两边同时对X求导,对Y求导,对Z求导结果.x^2+xy+y^2=4,两边同时对X求导得2x+y+xy'+2y*y'=0两边同时对Y求导得 2x*x'+x+x'y+2y=0两边同时对Z求导得 2x*x'+x'y+xy'+2y*y'=0 y^2-xy+e^x=1的导数y^2-xy+e^x=1求导y 隐函数求导问题e^(xy)=x+y+e-2 做这道题“两边关于x求导”是什么意思?e^(xy)(xy)'=1+y'e^(xy)(y+xy')=1+y' 这两步里为什么 x' 没有了?望详解 隐函数求导X^3-y^3-x-y+xy=2
