Answer
Question 1 (3 marks) [Differentiation and integration]
(a) Find ∫ (−6/x³) dx.
(a) Answer: 3/x² + c
- Integrate each term: ∫ axⁿ dx = a xⁿ+¹/(n + 1) + c.
- ∫ (−6/x³) dx = 3/x² + c.
Integrate term by term, then use a point on the curve to find the constant; for a definite integral subtract the value at the lower limit.
