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!
