Hello, I hope you are well. Attached are my questions in the image below.

Problem 17.3. Study the convergence of the following series: (1) S +oo (-1)"(3n+11) n=1 2n+7 (5) 5 - (-1)" sin(!). (2) E + 00 (6) +00 n=1 1=1 (-1)" sin( (3) too (-1)" 7/6 . 7 n=1 (-1)" tan (- MMMM MM (4) (-1) O (-1)" tan(-2). n=1 vn+3' 1=1 (9) n=1 (-1)" n2(1 - cos(1))
