Webn} converges pointwise. Solution: For every x in R, we have −1 √ n+1 ≤ sin(nx+3) √ n+1 ≤ 1 √ n+1 Moreover, lim n→∞ 1 √ n+1 = 0. Applying the squeeze theorem for sequences, we obtain that lim n→∞ f n(x) = 0 for all x in R. Therefore, {f n} converges pointwise to the function f ≡ 0 on R. Example 5.
