Question

( operatorname{Lt}_{x rightarrow frac{pi}{2}} frac{5 sin [cos x]}{[cos x]+2} )
( =underset{x rightarrow frac{pi}{2}}{left.frac{4}{2}+frac{5 sin left[cos frac{pi}{2}right.}{2}right]}{left[frac{left.cos frac{pi}{2}right]+2}{2}right.} )
( =frac{5(sin 0)}{0+2} )
( =frac{0}{2}=0 )

# If [] denotes the greatest integer function, in 5 sn[cosx] x- (cos.x]-2 is : ([.) denotes greatest integer function). A 0 B 1 Does not exist
