Find Partial Fractions Integration

Factor the denominator, decompose the rational expression, then integrate the simpler terms.

Formula: P(x)/Q(x) = sum of simpler partial-fraction terms when degree(P) < degree(Q)

Keep rates, balances, prices, and time periods on the same basis. An annual rate should not be combined with a monthly period unless the formula accounts for that conversion.

Check the final amount against the starting figure and rate. A large unexpected difference often points to a period or percentage entered in the wrong form.
