Please solve question 1 and 2 thanks

1. Decide whether E(n=1 to n=co)[(n+1)/(n2+2n+1)] is convergent or divergent using a) the Limit Comparison Test and b) the Integral Test. Explain your answers fully and carefully. You may assume for b) that the summand is decreasing. 2. Use the Ratio Test to decide whether E(n=1 to n=co) [(2n+1)!/{(n!)(n+1)!}] is convergent or divergent. Explain your answer fully and carefully
