\lim \limits_{{x \rightarrow 0}} k x \operatorname{cosec} x=\lim \limits_{{x \rightarrow 0}} x \operatorname{cosec} k x

, then

k=

View answer and explanation

Correct option: C

\pm 1

Option C (

\pm 1

) is correct because solving the equation

\lim \limits_{{x \rightarrow 0}} k x \operatorname{cosec} x=\lim \limits_{{x \rightarrow 0}} x \operatorname{cosec} k x

yields

k = \pm 1
