(sinθ + cosθ)/(sinθ - cosθ) = 7 হলে, tanθ =?

A 4/3

B 1/7

C 5/3

D 3/4

Solution

Correct Answer: Option A

দেওয়া আছে,
(sinθ + cosθ)/(sinθ - cosθ) = 7
বা, 7(sinθ - cosθ) = sinθ + cosθ
বা, 7sinθ - 7cosθ = sinθ + cosθ
বা, 7sinθ - sinθ = cosθ + 7cosθ
বা, 6sinθ = 8cosθ
বা, sinθ/cosθ = 8/6
∴ tanθ = 4/3
