求sin(x+y)=sinx+siny的导数
还有一题 e^x+x=e^y+y

两边求导：cos(x+y)*(1+y')=cosx+cosy*y'
y'=(cosx-cos(x+y))/(cos(x+y)-cosy)

e^x+1=e^y*y'+y'
y'=(e^x+1)/(e^y+1)

求sin(x+y)=sinx+siny的导数求下列导数：sin(x+y)=sinx+siny e^x+x=e^y+y 求函数z=sinx+siny+sin(x+y)(0 证明sin(x+y)sin(x-y)=sinx-siny sinx+siny=-1/3 cosx+cosy=1/2,求sin(x+y)的值. arcsin(sinx+siny)+arc(sinx-siny)=kπ/2,K为奇数,求sin^2x+sin^2y的值证明sin(x+y)=sinx*cosy+cosx*siny的过程求y=sinx三次方的导数 sin^3X 的导数,3在sin的右上角, 证明 [sin(2x+y)/sinx]-2cos(x+y)=siny/sinx 求证：sin(2x+y)/sinx-2cos(x+y)=siny/sinx 证明sinx+siny+sinz-sin(x+y+z)=4sin((x+y)/2)sin((x+y)/2)sin((x+ 求y=x^sinx 的导数
