Dec 21, 2020 · Example \(\PageIndex{2}\):Using Properties of Logarithms in a Derivative. Find the derivative of \(f(x)=\ln (\frac{x^2\sin x}{2x+1})\). Solution. At first glance, taking this derivative appears rather complicated. However, by using the properties of logarithms prior to finding the derivative, we can make the problem much simpler.

The natural logarithm is usually written ln(x) or log e (x). The natural log is the inverse function of the exponential function. They are related by the following identities: e ln(x) = x ln(e x) = x. Derivative Of ln(x) Using the Chain Rule, we get. Example: Differentiate y = ln(x 2 +1) Solution: Using the Chain Rule, we get.

The derivative from above now follows from the chain rule. If [latex]y=b^x[/latex], then [latex]\ln y=x \ln b[/latex]. Using implicit differentiation, again keeping in mind that [latex]\ln b[/latex] is constant, it follows that [latex]\frac{1}{y}\frac{dy}{dx}=\text{ln}b.[/latex] Solving for [latex]\frac{dy}{dx}[/latex] and substituting [latex]y=b^x[/latex], we see that
