find dy/dx at x=2 if y=6u^2-11and u=3x^2+2

find dy/dx at x=2 if y=6u^2-11and u=3x^2+2 Find out F(1)=?If dy/dx =1/2x,and f(e)=0 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 Find dy/dx if ln(y)=e^(6y)sin(4x),求 y`(x)=?如题 (x^2)dy+（y^2)dx=dx-dy 微积分given x^2=3y+xIn(y),find dy/dx,感激不尽..T-T if y=6x+1 then dy/dx=? 微分方程 dy/dx=(-2x)/y dy/dx=e^(-x^2) 要详细不走,每一个问号填一个数字或者式子find the gradient of the curve y=(x-1)(x-2) dy/dx=?at the point where x=7 at x=7find the points on the curvey=x(x-1)(x-2) dy/dx=?=11which have the same gradient =0=0=0x=?or Points are :( ,) an 参数方程x=at^2 y=bt^3求dy/dx 只是我看不懂y=4x3（这是三次方）+2x-5differentiate to find dy/dx 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 dy/dx=x/2y dy/dx=x+y 解方程y^2+x^2*(dy/dx)=x*y*(dy/dx) 求解微分方程x(dy/dx)^2-2(dy/dx)+4x=0, dy/dx=x+y Find d²y/dx² if 4x²−2y²= 9
