Find out F(1)=?If dy/dx =1/2x,and f(e)=0

Find out F(1)=?If dy/dx =1/2x,and f(e)=0 Find dy/dx if ln(y)=e^(6y)sin(4x),求 y`(x)=?如题 if y=6x+1 then dy/dx=? 二阶求导数Find d^2y/dx^2 if y^2+2y=4x^2+2x2y*dy/dx+2*dy/dx=8x+2dy/dx=(4x+1)/(y+1)d^2y/dx^2=(4(y+1)-4(x+1)(dy/dx))/(y+1)^2我不明白最后的一步.为什么那里要乘上dy/dx?按照除法则不是应该乘上y+1的导数吗?但是下一步 y=f[(x-1)/(x+1)],f'(x)=arctanx^2,求dy/dx,dy to find out more about singles day用if改写 To find out more about Singles Day 用if改写... find out find out. find dy/dx at x=2 if y=6u^2-11and u=3x^2+2 EXCEL公式的意思=MID($A1,FIND(市,$A1)+1,IF(ISERROR(FIND(区,$A1)),FIND(县,$A1),FIND(区,$A1))-FIND(市,$A1)) 例2.11为什么1=f'(x)dx/dy EXCEL 函数问题：MID($C$162,FIND(F,$C$162,FIND(=,$C$162,FIND(A5,$C$162,1)))+1MID($C$162,FIND(F,$C$162,FIND(=,$C$162,FIND(A5,$C$162,1)))+1,FIND(/,$C$162,FIND(=,$C$162,FIND(A5,$C$162,1)))-FIND(F,$C$162,FIND(=,$C$162,FIND(A5,$C$162,1 微积分 求方程式Find the equation of the curve passing through the point (1,1/12) such that at all points on the curve y=f(x) with [(5-3x)^2]dy/dx=1找出曲线方程,通过点(1,1/12) 并且[(5-3x)^2]dy/dx=1 突然不明白一道微积分的题：1=f'(x)·dx/dy 两边同时求导为什么是：0=f”(x)·dx/dy·dx/dy+f'(x)·d^2x/dy^2 ?其中为什么有两个dx/dy?f'(x)求导不直接就是f”(x)了么,不是应该是0=f”(x)·dx/dy·+f'(x)·d^2x/dy^2 what if 句子意思what if you've been able to find out 这里的what if 什么意思. If f(x)=log(x).write out the domain and range of the function. 为什么dy=f'(x)dx
