( e^(x y)-e^x)dx (e^(x y) e^y)dy=0
e^x+e^y=sin(xy),求dy/dx.怎么求

将y看成是关于x的函数即y=f(x)我们在求导的同时要记得y也要对x求导即dy/dx我们两边分别对x求导得e^x+e^y*dy/dx=cos(xy)*(y+x*dy/dx)移项e^x-y*cos(xy

积分∫dx /(e^x+e^-x)

将被积函数分子,分母同乘以e^x得:被积函数=e^x/(e^2x+1)=d(e^x)/e^2x+1,令u=e^x,则原式=∫du/(u^2+1)(u>0)=∫[d(tanA)]/[1+(tanA)^2

xy-e^x+e^y=0,求dy/dx|x=0?

将xy-e^x+e^y=0两边取导得:ydx+xdy-e^xdx+e^ydy=0解得:dy/dx=﹙y--e^x﹚/﹙x-+e^y﹚当x=0时,∴e^y=1,y=0∴dy/dx|x=0=(0-1)/﹙

积分 dx/[e^x+e^(2-x)]

令t=e^x,则dt=e^x*dx=tdxdx/[e^x+e^(2-x)]=dx/[t+(e^2/t)]=tdx/(t^2+e^2)=dt/(t^2+e^2)令t/e=u,t=eu,则dt=edu,d

已知e^y+e^x-xy^2=0,求dy/dx

y'e^y+e^x-y²-2xyy'=0y'=(e^x-y²)/(2xy-e^y)即:dy/dx=(e^x-y²)/(2xy-e^y)祝你开心!希望能帮到你,如果不懂,请

∫(e-e^x)dx

∫(e-e^x)dx=ex-e^x+C其中C为常数不定积分是导数的逆运算,你应该会的呀

xy=e^(x+y),求dx/dy

ydx/dy+x=(e^x)(e^y)dx/dy+(e^x)(e^y)dx/dy=[(e^x)(e^y)-x]/[y-(e^x)(e^y)]dx/dy=(xy-x)/(y-xy)dx/dy=x(y-1

不定积分 /1e^x-e^(-x)dx

点击放大,荧屏放大再放大:

∫1/(e^x+e^(-x))dx,

原式=∫e^x/(e^2x+1)dx=∫de^x/(e^2x+1)=arctan(e^x)+C

∫e^x(e^-x +2)dx

原式=∫(1+2e^x)dx=∫dx+2∫e^xdx=x+2e^x+C

求e^(x+e^x)dx=

e^(x+e^x)dx=e^e^x+c

积分dx/[e^x+e^-x]

你算错了~答案是对滴

siny+e^x-xy^2=0,求dy/dx

siny+e^x=xy^2,两边求微分,cosydy+e^xdx=d(xy^2)cosydy+e^xdx=y^2dx+2xydy整理,得(e^x-y^2)dx=(2xy-cosy)dydy/dx=(e

求e^x+xy=e所确定的隐函数y的导数dy/dx

两边分别求x的导数得:e^x+(y+xy')=0,即y'=-(e^x+y)/x,即:dy/dx=-(e^x+y)/x

已知xy-e^x+e^y=0,求dy/dx

对xy-e^x+e^y=0求微分得ydx+xdy-e^xdx+e^ydy=0(y-e^x)dx+(x+e^y)dy=0dy/dx=(x+e^y)/(e^x-y)

已知xy+e^y=e...求dx/dy|x=0

x=0,e^y=e,y=1xy+e^y=ey+xdy/dx+e^ydy/dx=0dy/dx=-y/(x+e^y)dx/dy|x=0=-1/e

求dy/dx+y/x=e^(xy)

令e^(xy)=u,y=lnu/xDy/dx=[(x/u)*(du/dx)-lnu]/x²,∴(1/ux)*(du/dx)-lnu/x²+lnu/x²=u即du/u

求导:xy=x-e^xy,求dy/dx

答:xy=x-e^(xy)e^(xy)=x-xy=x(1-y)两边对x求导:(xy)'e^(xy)=1-y-xy'(y+xy')e^(xy)=1-y-xy'ye^(xy)+xy'e^(xy)+xy'=
