7.4 Partial Fractions We integration!
Tips for Integration • Try anti-differentiation first • Try u-substitution • Check for Inverse trig forms • If there is an extra variable in the denominator, try completing the square • Integration by Parts • Check for the common forms • Integration by Partial Fractions • Try 1 of the 3 cases • Use Algebra! • Don’t be afraid to mix multiple techniques in 1 problem!
3 Cases for Partial Fractions • Case I – The denominator has distinct factors • Case II – The denominator has repeating factors • Case III – The denominator has a quadratic that won’t factor • If the degree in the numerator is higher than the degree in the denominator, use long division first.
Case III – The denominator has a quadratic that won’t factor
