| Topic | Integration by Substitution |
| Type | Definite integral with simple linear/polynomial substitution |
| Difficulty | Moderate -0.3 This is a straightforward integration question requiring a simple substitution or recognition of the reverse chain rule. It's slightly easier than average because it's a single-step problem with clear bounds and a standard integrand form, though students must handle the chain rule correctly and evaluate definite integral limits. |
