| Topic | Indefinite & Definite Integrals |
| Type | Integration with algebraic manipulation |
| Difficulty | Moderate -0.8 This is a straightforward integration question testing basic techniques. Part (i) requires expanding brackets then integrating polynomials (standard C2 skill), and part (ii) is direct integration of x^(-1/2) with simple limits. Both are routine textbook exercises with no problem-solving or insight required, making this easier than average. |
