If lim an does not exist or if lim an 0, then the series
an is divergent.
n→∞
n=1
1) Use the method of Test For Divergence to determine which of the following series is divergent.
n2 + 1
a)
n3 + 2
n=1
5n? + 4x + 8
In (
b)
3n2 – 2x + 7
n=1
2) For the method of Test For Divergence, we use it to determine a series is divergent or not. NEVER USE
TEST FOR DIVERGENCE TO CONCLUDE A SERIES IS CONVERGENT!!!! This
lim
means,
an = 0
%3D
does not imply the series converges.
For the second problem, please give an example of a series such that lim an
0 but the series actually
diverges.
