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! WebDifferentiate log x 3 ? Advertisement Remove all ads Solution Let y Let y = log x 3 ⇒ y = log 3 log x [ ∵ log a b = log b log a] Differentiate it with respect to x we get Differentiate it with respect to x we get, d y d x = d d x ( log 3 log x) = log 3 d d x ( log x) − 1

When the logarithmic function is given by: f (x) = log b (x). The derivative of the logarithmic function is given by: f ' (x) = 1 / (x ln(b) ) x is the function argument. WebTo find the derivative of log_e (x^2+1)^3 use chain rule. You will often find many cases like expoential, trigonmetric, logarithmic, inverse trigonometric expressions in which you need to use chain rule so can find the derivative so you need to be comfortable with it.
