I keep getting “Methods of integration” questions wrong in Integration. What's the trap?
reaching for by-parts when a simple substitution works.
The usual trap: reaching for by-parts when a simple substitution works. How to avoid it: try substitution first; use by-parts for products like x·e^x. Go back to the definition — substitution, integration by parts, and partial fractions handle most integrals.
