Need help taking the limit

lim(n->infinity) cos(n*pi)/n

Consider the following limit (Image) We can simplify this limit by rewriting it as an expression without absolute values as follows (Answer) We can then cancel off a common factor in the numerator and denominator, thus simplifying our limit to (Ans) We can then evaluate the limit directly and find that its value is (Answer)
