Question

The value of the limit Limx→0 (cos x)cot2 x is _______________(a) 1 (b) e(c) e1/2(d) e-1/2 *​

Answer 1

Step-by-step explanation:

happy maha shivratri of all

Answer 2

Answer:

(d) e-1/2

Step-by-step explanation:

Given, Limx→0 (cos x)cot² x

= Limx→0 (1 + cos x – 1)cot² x

= eLimx→0 (cos x – 1) × cot² x

= eLimx→0 (cos x – 1)/tan² x

= e-1/2
