If it converges, ±nd the limit justifying your steps. If it diverges, explain why. a ) a n = (-1) n n 6 n 7 + 30 n 2 b ) a n = ln( n ) 6 + ln(3 n ) c ) a n = (-1) n cos(1 /n ) Determine if the following integrals are convergent or divergent. Evaluate those that are convergent. 7) (8 pts) I ∞-∞ 4 x 3 e-x 4 dx 8) (12 pts) I π/ 2 sec 6 θ dθ [Hint: First separately evaluate the inde±nite integral. If you are unable to do so, at least write the de±nition of how this speci±c improper integral is de±ned.] 9) (5 pts) Determine the FORM of the partial fraction decomposition for x 3-4 ( x 3-2 x 2 + x )( x 2 + 4) 3 .
