ln(1)/[1-x]?

d/dx(u/v)=(v*du/dx-u*dv/dx)/(v2)

d/dx(ln(1)/[1-x])=[(1-x)*d/dx(ln1)-ln1*d/dx(1-x)]/[(1-x)2]

-The derivative of ln1 is:

d/dx(lnu)=(1/u)*d/dx(u)

d/dx(ln1)=(1/1)*d/dx(1)

d/dx(ln1)=(1)*d/dx(1)

d/dx(ln1)=d/dx(1)

-The derivative of 1-x is:

d/dx(u-v)=du/dx-dv/dx

d/dx(1-x)=d/dx(1)-d/dx(x)

d/dx(ln(1)/[1-x])=[(1-x)*d/dx(1)-ln1*(d/dx(1)-d/dx(x))]/[(1-x)2]

-The derivative of 1 is 0 because it is a constant.

-The derivative of x is:

d/dx(xn)=nxn-1

d/dx(x)=1*x1-1

d/dx(x)=1*x0

d/dx(x)=1*(1)

d/dx(x)=1

d/dx(ln(1)/[1-x])=[(1-x)*(0)-ln1*(0-1)]/[(1-x)2]

d/dx(ln(1)/[1-x])=[-ln1*(-1)]/[(1-x)2]

d/dx(ln(1)/[1-x])=[ln1]/[(1-x)2]

But you see, ln1 is equal to 0:

d/dx(ln(1)/[1-x])=[0]/[(1-x)2]

d/dx(ln(1)/[1-x])=0

What is the third derivative of lnx?

The first derivative of ln x is 1/x, which (for the following) you better write as x-1.Now use the power rule:Second derivative (the derivative of the first derivative) is -1x-2, the third derivative is the derivative of this, or 2x-3. You may now wish to write this in the alternative form, as 2 / x3.

What is the derivative of ln 1- x?

The derivative of ln x is 1/x. Replacing the expression, that gives you 1 / (1-x). By the chain rule, this must then be multiplied by the derivative of (1-x), which is -1. So, the final result is -1 / (1-x).


What is the derivative of 2lnx?

The derivative of ln x is 1/x The derivative of 2ln x is 2(1/x) = 2/x


What is the derivative of ln1 divided by x?

Given y=ln(1/x) y'=(1/(1/x))(-x-2)=(1/(1/x))(1/x2)=x/x2=1/x Use the chain rule. The derivative of ln(x) is 1/x. Instead of just "x" inside the natural log function, it's "1/x". Since the inside of the function is not x, the derivative must be multiplied by the derivative of the inside of the function. So it's 1/(1/x) [the derivative of the outside function, natural log] times -x-2=1/x2 [the derivative of the inside of the function, 1/x] This all simplifies to 1/x So the derivative of ln(1/x) is 1/x


What is the derivitive of ln10x?

The derivative of ln(x) is 1/x. Therefore, by Chain Rule, we get:[ln(10x)]' = 1/10x * 10 = 1/xUsing this method, you can also infer that the derivative of ln(Ax) where A is any constant equals 1/x.


What is the derivative of -1?

The derivative of a linear function is always its gradientIn the function y = x-1, the gradient is 1 as 1 is the co-efficient of 1x.
