Question 40
IntegrationEvaluate ∫2π (sec2x − tan2x)dx.
- A.π/2
- B.π − 2
- C.π/3
- D.π + 2
Show the answer and explanation
Answer: B (π − 2)
Explanation
sec²x − tan²x = 1, so the integral is [x] from 2 to π = π − 2.
Evaluate ∫2π (sec2x − tan2x)dx.
Answer: B (π − 2)
sec²x − tan²x = 1, so the integral is [x] from 2 to π = π − 2.
