(6 points) Decide whether each of the following series converges. If a given series converges, compute its sum. Otherwise, enter INF if it diverges to infinity, MINF if it diverges to minus infinity, and DIV otherwise. eA7 1. Σ (en_ e7(n+1)) n=1 MINF 2. Σ(sin(-2n)-sin(-2(n +1))) n=1 3. -sin(2) n+ 1 n=1
