Answer We have tan A cot A = 4 Squaring both sides, tan 2 A cot 2 A 2 = 16 (since cot A = 1 / tan A) So, tan 2 A cot 2 A = 14 Again squaring both sides, we have tan 4 A cot 4 A 2 = 196 So, tan 4 A cot 4 A = 194 The correct option is A Related What is the angle of elevation of the sun when the · To find \(\frac{1tan^2A}{1cot^2A}\) Consider \(\frac{1tan^2A}{1cot^2A}\) ∵ 1 tan 2 A = sec 2 A and 1 cot 2 A = cosec 2 A ∴ \(\frac{1tan^2A}{1cot^2A}\) = \(\frac{sec^2A}{cosec^2A}\) = \(\frac{1/cos^2A}{1/sin^2A}\) \(\Big∵secA\frac{1}{cosA}\,and\,cosecA=\frac{1Let t = 1 − x ⇒ x = 1 − t x → 1 ⇒ t = 0 Now lim t → 0 t tan (2 π (1 − t)) = lim t → 0 t tan (2 π − 2 π t) = lim t → 0 t cot (2 π − t) = lim t → 0 t a n 2 π t t Now multiply & divide the above expression by 2 π we get = lim t → 0 π 2 (t a n 2 π t 2 π t ) = π 2
