can i use p series test to confirm that the series will converge..

where p = 2..

if my

**a**n = 1 / (n+1)^2

can i use p series test to confirm that the series will converge..

no it wont work. the p series test only works when the denominator is n raised to a power 1/n or 1/n^2 or 1/n^(3/2)

even when you indirectly use the p series test with direct comparison or limit comparison an must still be in the form of 1/n

the integral test works the integral 1/(x+1)^2 ,x,0,infinity converges thus the series converges ... the sum however is not found that way. - Dec 9th 2009, 11:19 AMnameck
ok..so.. what test should i use to know whethere it is convergence or divergence?
