  1. If tan θ + cot θ = 2, then the value of tann θ + cotnθ (0° < θ < 90°, n is an integer) is
    1. 2
    2. 2n
    3. 2n
    4. 2n + 1
Correct Option: A

tan θ + cot θ = 2

⇒ tan θ +
1
= 2
tan θ

⇒ tan⊃ θ - 2tan θ + 1 = 0
⇒ (tan θ - 1)² = 0
⇒ tanθ = 1 0 ⇒ tanθ = 1
∴ cot θ = ⇒ θ= 45°
∴ tann 45° + cotn 45° = 1 + 1 = 2
