This document discusses integral partial, a type of integral calculation. It begins by introducing integrals and stating that integral partial is used when an integral cannot be solved through regular substitution. The document then provides:
1) The formula for integral partial as ∫u dv = uv - ∫v du.
2) An example problem demonstrating how to apply the integral partial formula to calculate the integral of 2x(3x-5)6 dx.
3) Additional example problems and their step-by-step solutions using both the integral partial formula and tabular method.
