Exponential and logarithmic functions arise in many real-world applications, especially those involving growth and decay. Substitution is often used to evaluate integrals involving exponential …
The derivative of the logarithm \ln x lnx is \frac {1} {x} x1, but what is the antiderivative? This turns out to be a little trickier, and has to be done using a clever integration by parts. The logarithm is a basic function from which many other functions are built, so learning to integrate it substantially broadens the kinds of integrals we can tackle.

5.2 The Natural Logarithmic Function: Integration Use the Log Rule for Integration to integrate a rational function.
Example 1: Integrate the function ∫ 1 2 1 8 − 3 x d x Solution: We can recognize this is an integral of logarithmic form because the denominator is to the power of -1 (e.g., it can be written as (8 − 3 x) − 1.
The integral of any quotient whose numerator is the differential of the denominator is the logarithm of the denominator.
