If and , where does not lie in the third quadrant, then is equal to
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Given, cosθ=-32<0 and θ does not lie in third quadrant. ∴ θ must be lying in 2nd quadrant. ⇒ tanθ=-13 and cotθ=-3 ...(i) As, sinα=-35, thus α lies in 3rd or 4th quadrant. If α is in third quadrant, then…
