Exercise · ZW-INTEGRATION-BY-PARTS-008 · ★☆☆ Basic
According to the LIATE rule, which family of functions should be chosen first as \(u\)?
Choose one option.
Show answer
- D. Logarithmic
Explanation
LIATE orders logarithmic, inverse trig, algebraic, trigonometric and exponential. The first, logarithmic, is the one to take as \(u\).
Review the concept: Integration by parts
Integration by parts is a technique for integrating products of functions, derived from the product rule. It transforms \(\int u\,dv\) into \(uv-\int v\,du\).
\[\int u\,dv=uv-\int v\,du\]
