Trigonometry MCQs from the NET-pattern papers
Try each one before opening the answer. Each comes with a short explanation.
- Q1 · NUST NET Past Paper 07 · Trigonometry
(1 − cos 2x)/sin 2x is equal to:
- A.tan x
- B.cot x
- C.sin x
- D.sec x
Show answer
Answer: A. tan x — (1 − cos 2x)/sin 2x = 2sin²x/(2 sin x cos x) = tan x.
- Q2 · NUST NET Past Paper 08 · Trigonometry
The length of the arc that subtends an angle of 45° at the centre of a circle of radius 8 cm is:
- A.4π cm
- B.2π cm
- C.π cm
- D.8π cm
Show answer
Answer: B. 2π cm — θ = 45° = π/4 rad; arc length = rθ = 8 × π/4 = 2π cm.
- Q3 · NUST NET Past Paper 05 · Trigonometry
An angle of 7π/4 radians is equal to:
- A.315°
- B.305°
- C.270°
- D.330°
Show answer
Answer: A. 315° — 7π/4 × 180°/π = 315°.
