LIATE suggests which factor to differentiate (assign to uu) based on the order: Logarithmic, Inverse trigonometric, Algebraic, Trigonometric, Exponential. However, it is not an absolute rule.

Conditions: The integrand involves a product of functions from different LIATE categories.; The user is selecting uu and dvdv for integration by parts.

Integration by parts replaces an integral of u dvu \, dv with uvuv minus an integral of v duv \, du. The goal is to choose factors that make the new integral easier to evaluate.

Conditions: The integrand can be expressed as a product of two functions.; The chosen factors uu and dvdv must be differentiable and integrable respectively.
