Derivative of the Logarithmic Function. Now that we have the derivative of the natural exponential function, we can use implicit differentiation to find the derivative of its inverse, the natural logarithmic function.

Feb 09, 2007 · It's 1/(tanh(x/2)) multiplied by the derivative of tanh(x/2), which is either (1/2) (sech(x/2))^2 or-(1/2) (sech(x/2))^2, I can't remember which but you can look it up as quickly as I can work it out! Anyway, you can see that comes to. 1/(2 sinh(x/2) cosh(x/2)) = cosech (x), I think. Or its negative!! I still haven't worked that out.

The derivative of ln(x) is 1/x, so f ' (x) = 1/x. The derivative of x is 1, so g ' (x) = 1. Great! We have all our parts, now let's plug them into the quotient rule and find the derivative of ln(x ...

This mirror-image property will help us a lot as we take derivatives of inverse functions. The graphs of a function and its inverse are mirror images across the line y = x . If (x, y) is on f(x), then (y, x) is its mirror-image point across y = x, and the slope of f(x) at x is the reciprocal of the slope of f -1 (x) at y.

f (x) = ln(x) The derivative of f(x) is: f ' (x) = 1 / x. Integral of natural logarithm. The integral of the natural logarithm function is given by: When. f (x) = ln(x) The integral of f(x) is: ∫ f (x)dx = ∫ ln(x)dx = x ∙ (ln(x) - 1) + C. Ln of 0. The natural logarithm of zero is undefined: ln(0) is undefined

Plotting f(x)=ln(x) then Derivative(f) gives the full function 1/x, including for negative x. Is there a reason why the negative is plotted? If the function doesn't return a real value for the input it appears strange...

- 24.3.2 Example Find the derivative of y= (lnx)sinx (1 <x<ˇ). Solution We use logarithmic di erentiation: lny= ln(lnx)sinx = (sinx)ln(lnx); so, using implicit di erentiation, we get d dx [lny] = d dx [(sinx)ln(lnx)] 1 y y0 = d dx [sinx]ln(lnx) + (sinx) d dx [ln(lnx)] 1 y y0 = (cosx)ln(lnx) + (sinx) 1 lnx 1 x y0 = y (cosx)ln(lnx) + sinx xlnx y0 ...
