Let f(x)={k cos xπ −2x,where x≠π23,where x=π2and if limx→π2f – InterviewSolution

1.	Let f(x)={k cos xπ −2x,where x≠π23,where x=π2and if limx→π2f(x)=f(π2), find the value of k.
Answer» Let $f (x) = {\begin{matrix} \frac{k c o s x}{π - 2 x}, & where x \neq \frac{π}{2} 3, & where x = \frac{π}{2} and if \end{matrix}$ ${lim}_{x \to \frac{π}{2}} f (x) = f (\frac{π}{2})$ , find the value of k.
