Test Condition Conclusion Note If {b,} is positive, decreasing sequence and lim b, = 0, then Z a, =E (-1)" b, is convergent. b, = |anl Remainder = Error = |S- S,I < bn1 Error found by using the nth partial sum is less than the first omitted term.

INTEGRAL TEST Assume f(n) = an , and Use the integral test if the integral is easy to evaluate. 3) then the test is inconclusive. If, f(x)dx is convergent (divergent), then (for series with positive terms) f(x) is positive, decreasing and continuous on [1, 0). The integral is always an improper integral, so (S(x)dx = lim [" f(x)dx. a, is also convergent (divergent).
