# Tabular integration by parts

This page will try to visualize tabular integration by parts, which
makes the process of doing integration by parts a whole lot easier!

To keep things simple, we will keep to simple functions, like an algebraic term
multiplied with a trigonometric term, with integer coefficients.
For example, finding ∫ ax^{n} cos x dx.

## User input

You are about to integrate:

∫ ax^{n} f(x) dx

For performance reasons, n must not be greater than 100.

Also n must be a positive integer. Any attempt to enter a negative number will be made
positive. Any attempt to enter fractional number we will trancate it into integer.
