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! Web1.5.1: The Relationship Between Logarithmic and Exponential Functions. We saw earlier that an exponential function is any function of the form , where and . A logarithmic function is any function of the form , where and . It is no coincidence that both forms have the same restrictions on because they are inverses of each other.

Let a > 0 and set f(x) = ax — this is what is known as an exponential function. Let's see what happens when we try to compute the derivative of this function just using the definition of the derivative. df dx = lim h → 0 f(x + h) − f(x) h = lim h → 0 ax + h − ax h = lim h → 0ax ⋅ ah ... the matchbox diary by paul fleischman
