Take Free Practice Test On 2026 JAMB UTME, Post UTME, WAEC SSCE, GCE, NECO SSCE
  • A (2/3) cos 3x + c
  • B (1/3) cos 3x + c
  • C (-1/3) cos 3x + c
  • D (-2/3) cos 3x + c
Correct Answer: Option C
Explanation:
\(\int \sin 3x \mathrm d x = - \frac{\cos 3x}{3} + c\)
= \(-\frac{1}{3} (\cos 3x) + c\)
