parts.
In calculus, and more generally in mathematical analysis, integration by parts or partial integration is a process that finds the integral of a product of functions in terms of the integral of the product of their derivative and antiderivative. It is frequently used to transform the antiderivative of a product of functions into an antiderivative for which a solution can be more easily found. The rule can be thought of as an integral version of the product rule of differentiation.

Mathematician Brook Taylor discovered integration by parts, first publishing the idea in 1715. More general formulations of integration by parts exist for the Riemann–Stieltjes and Lebesgue–Stieltjes integrals. The discrete analogue for sequences is called summation by parts.
I have one of the original Black LTT 1301, it's got the Nordic and Aridus parts vs the GGG parts. It's a solid shooter and a ton of fun, it has the Rob Haught Aimpoint Micro mount installed. I have an aimpoint for it, KAC cap and plastic covers. Has less than 50 rounds shot through it. I find I...
