Partial Fractions

Functions of $x$ that can be expressed in the form $P(x)/Q(x)$, where both $P(x)$ and $Q(x)$ are polynomials of $x$, is known as rational fraction. A rational fraction is known to be a proper fraction if $P(x)$ is less in degree power than $Q(x)$. Example of proper fraction is...
