Study Notes
Integration by Parts
- The purpose of integration by parts is to integrate products of functions by transforming them into easier integrals or integrals that can be evaluated more easily.
Relationship to Product Rule
- Integration by parts is related to the product rule of differentiation, as it can be seen as the inverse operation of the product rule.
History
- The discovery of integration by parts is attributed to Scottish mathematician Brook Taylor.
General Formulation
- A more general formulation of integration by parts exists for integrating functions with multiple variables, such as multivariate functions.
Discrete Analogue
- The discrete analogue for sequences of integration by parts is called summation by parts, which is used for summing products of sequences.
