Derivative of log x 3
Webwhere ′ is the derivative of f. Intuitively, this is the infinitesimal relative change in f; that is, the infinitesimal absolute change in f, namely ′, scaled by the current value of f.. When f is a function f(x) of a real variable x, and takes real, strictly positive values, this is equal to the derivative of ln(f), or the natural logarithm of f.This follows directly from the chain rule: WebExample 4. Suppose f(x) = ln( √x x2 + 4). Find f ′ (x) by first expanding the function and then differentiating. Step 1. Use the properties of logarithms to expand the function. f(x) = ln( √x x2 + 4) = ln( x1 / 2 x2 + 4) = 1 2lnx − ln(x2 + 4) Step 2. Differentiate the logarithmic functions. Don't forget the chain rule!
