Correct answer: (A) 11

Explanation

Both numerator and denominator → −∞, so use L'Hospital's rule: the ratio of derivatives is (2 cot 2x)/(cot x) = 2 tan x / tan 2x → 2 · (1/2) = 1 as x → 0.अंश और हर दोनों → −∞ हैं, इसलिए L'Hospital नियम लगाएँ: अवकलजों का अनुपात (2 cot 2x)/(cot x) = 2 tan x / tan 2x → 2 · (1/2) = 1, जब x → 0।
