2. Evaluate the following limits using an appropriate function and its upper or lower sums. a) limn+00 (sin + sin 2 + ...+ sin ). Hint: Use the function f(x) = sin(rx), and an appropriate partition of the interval [0, 1], then imitate the proof in the notes/video. 3n b) limn0 n + (en +en + . .+e). Hint: Choose an appropriate function, an appropri- ate partition, and then use the limit of an upper upper sum as in a).
