How to solve a partial fractions problem

  1. Factor the denominator

  2. Split up the denominator into two (or more) fractions added together with A and B as the numerators

  3. Multiply by a common denominator

  4. Set that equal to the original numerator

  5. Solve for A and B

  6. Plug into integral and solve

Geometric Series

98
New cards

Test for Divergence

Do the limit test and the series is divergent if lim≠0

99
New cards

If f(x) is continuous, positive, and decreasing then ∑n=1 an is convergent if and only if ∫1 f(n) dn is convergent.

If it is divergent then the series is divergent.

Integral test

New cards

Any power greater than 1 is convergent.

Any power less than 1 is divergent
