Y=xloga(x^2+x-1) Y=log2((x-1)/(x+1)) 求导数,Y=xloga(x^2+x-1) Y=log2((x-1)/(x+1))求导数,
Y=xloga(x^2+x-1) Y=log2((x-1)/(x+1)) 求导数,
Y=xloga(x^2+x-1) Y=log2((x-1)/(x+1))
求导数,
Y=xloga(x^2+x-1) Y=log2((x-1)/(x+1)) 求导数,Y=xloga(x^2+x-1) Y=log2((x-1)/(x+1))求导数,
1:
y'=x*[loga(x^2+x-1)]'+loga(x^2+x-1)
=x*(2x+1)/[lna*(-1 + x + x^2)]+loga(x^2+x-1)
=(2x^2+x)/[lna*(-1 + x + x^2)]+loga(x^2+x-1)
2:
y'=(x+1)/[Ln2(x-1)]*[(x - 1)/(x + 1)]'
=(x+1)/[Ln2(x-1)]*[(x+1)-(x-1)]/[(x+1)^2]
=2/[( x^2-1) Ln2]
复合求导：dy/dx=loga(x^2+x-1)+(2x+1)*{1/[(x^2+x-1)*lna]}
y=2log((x-1)/(x+1))
dy/dx=4/(x+I)^2*{1/[(x-1)/(x+1)*lna]}
Y=xloga(x^2+x-1) Y=log2((x-1)/(x+1)) 求导数,Y=xloga(x^2+x-1) Y=log2((x-1)/(x+1))求导数,
logx (x^2 - 2) = 1 求Xloga (x^2 - x -5) = 0求X不知分给谁好了!
若y=x方log2 a+2xloga 2+8的图像在x轴的上方,求a的范围!（是x方乘以以2为底a的对数+2x乘以以a为底2的对数+8）
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
设y^3+3x^2y+x=1确定y是x的函数,求y'及y'l（x=0）
若根号2x-y+ly+1l=0求【（x-y）的平方+（x+y）（x-y）】÷2x的平方根
C语言 三角函数 b=atan(Y/X)+(acos((X*X+Y*Y-2*L*L)/2*L*L))/2;结果b是弧度还是度数?还有acos((X*X+Y*Y-2*L*L)/2*L*L)中的(X*X+Y*Y-2*L*L)/2*L*L有范围限制吗
设z=ln(x+y/2x),求{əz／əy]l(1,0)
L:x^2+y^2-2x-1=0正向,求∮[e^(x^2+y^2)dx+(2x^2+x)dy]/(x^2+y^2)
l=x^2+y^2+根号下(x^2+y^2 )化简成y关于l,x的式子.
若lx-3l+ly-2l=0,则x+y= ,x-y=
l x-3l与I 2y+3I互为相反数则x+y=
若根号x-1+lx+y-2l=0
已知x,y是有理数,且|x+y-1l+(-x+2y+1)²=0,求x,y的值.
绝对值若lx-2y+1l+lx+y-5l=0则x=y=
(2009.呼和浩特)若lx-2y+1l+l2x-y-5l=0,则x+y=
若(x+y-5)^2+lx-y+3l=0x^2-y^2=?
lx-y+3l+（x+y）^2=0,则x+3y块
