Integrals Of Rational Expressions ((link)) — Circuit Training
One of the most common pitfalls in integrating rational expressions is forgetting the requirement that the degree of the numerator must be less than the degree of the denominator.
When deg(P) ≥ deg(Q): Example: ∫ (x² + 1)/(x+2) dx → divide to get x - 2 + 5/(x+2), then integrate term-by-term. Circuit Training Integrals Of Rational Expressions
