TopicIndefinite & Definite Integrals
TypePure definite integration
DifficultyModerate -0.8 This is a straightforward integration question requiring only basic power rule application (including negative powers) and definite integral evaluation. The techniques are routine for C2 level with no problem-solving or conceptual challenges—simply apply standard rules and substitute limits. Worth 5 marks but mechanically simpler than a typical multi-part question.
