sin 30° = ?

  1. √3/2
  2. 1/2
  3. 1
  4. 0
Show answer and solution

Correct answer: B. 1/2

1. Standard value: sin 30° = 1/2. 2. From the 30-60-90 right triangle ratios. _Source: TSICET 2024 PYQ Q.113 (Shift 1, Trigonometry)_

cos 60° = ?

  1. √3/2
  2. 1/2
  3. 0
  4. 1
Show answer and solution

Correct answer: B. 1/2

1. Standard value: cos 60° = 1/2. 2. From the unit circle. _Source: TSICET 2024 PYQ Q.114 (Shift 1, Trigonometry)_

If tan θ = 1, what is θ (acute)?

  1. 45°
  2. 30°
  3. 60°
  4. 90°
Show answer and solution

Correct answer: A. 45°

1. tan 45° = sin 45°/cos 45° = (√2/2)/(√2/2) = 1. 2. So θ = 45°. _Source: TSICET 2024 PYQ Q.115 (Shift 1, Trigonometry)_
