y=xsin 2x,求dy

y=xsin 2x,求dy (2xsin(y/x)-ycos(y/x))dx+(xcos(y/x)+1)dy=0 求y y=2xsin(2x+5)求导数! 设方程[A(y)]²+xsin[πA(y)]+2x-3=0,确定y是x的隐函数,A(y)可微且A(0)=A'(0)=1,求dy/dx|y=0 y=x^2x,求dy y=sinx/x^2,求dy y=x×2^arcsinx 求dy y=e^-x^2,求dy y=(tanx)/x^2,求dy y=(cos^2x) 求dy 高数求导（dy/dx）习题设由下列方程确定y是x的函数,求dy/dx(1)cos(x^2 +y)=x求下列参数方程所确定的函数y=f(x)的导数dy/dx(1)x=(e^t)sint,y=(e^t)cost.(1)-[1+2xsin(x^2 +y)]/[sin(x^2 +y)](2)cost-sint/sint+cost 求不定积分,xsin^2x x^y-y^x=2,求dy/dx 求dy/dx=(x-y+5)/(x+y-2) x^y=y^x,求dy. y=2xsin(2x+5)的导数怎么求,要过程 y=2xsin(2x+5),求函数的导数 求下列函数的导数 y=2xsin(2x+5)
