Question

HELP PLEASE.

Answer 1

When Using the Comparison Test to test for Divergence/Converge,

Do we need to compare something that is bigger than the original for Divergence and compare something that is smaller than the original for Convergence....

or vice versa?

Answer 3

Yes, we are.

Answer 4

huh?

Answer 5

Like this : Suppose you need find out whether A is convergent or divergent and use comparison test.

By the test, A < B, if B converges, then A converges. You need to prove A < B first.

A > B , if B diverges, then A diverges. Again, you need to prove A > B first.

Thanks!
