Let us assume $f(x)$ and $g(x)$ be two polynomials and to find the integral of the type $$\frac{{f(x)}}{{g(x)}}$$ which is a rational algebraic function of $x$ following two cases are there:
Case I: When degree of $f(x)$ is less than degree of $g(x)$ then $\frac{{f(x)}}{{g(x)}}$ is called proper rational function which is expressed as the sum of rational functions and solved using partial fractions.
The partial fractions depends on the nature of the factors of denominator $g(x)$ due to which the following different types are there when the factors of $g(x)$ are:
