THE COMPARISON TESTS In the comparison tests the idea is to compare a given series with a series that is known to be convergent or divergent. THEOREM: (THE COMPARISON TEST) divg Determine whether the series converges or diverges. Example:

THE COMPARISON TESTS THEOREM: (THE LIMIT COMPARISON TEST) Determine whether the series converges or diverges. Example: With positive terms both series converge or both diverge.

THE COMPARISON TESTS THEOREM: (THE LIMIT COMPARISON TEST) Determine whether the series converges or diverges. Example: With positive terms both series converge or both diverge. Determine whether the series converges or diverges. Example: Notice that in testing many series we find a suitable comparison series by keeping only the highest powers in the numerator and denominator. REMARK: Converge, then convg and divg, then divg and
