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: WebCalculus. Find the Derivative - d/dx y = log of 3x. y = log(3x) y = log ( 3 x) Differentiate using the chain rule, which states that d dx [f (g(x))] d d x [ f ( g ( x))] is f '(g(x))g'(x) f ′ ( g …

WebThe derivative of log x (base 10) with respect to x is denoted by d/dx (log x) or (log x)'. Thus, d/dx(logₐ x) (or) (logₐ x)' = 1/(x ln a) d/dx(log x) (or) (log x)' = 1/(x ln 10) Since the … imply sign in latex

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!
