The primary learning objective is to recognize standard functional forms and apply the corresponding integration rules. Strategies often include simplifying the integrand through algebraic manipulation before performing the integration to find the general antiderivative. In partial fraction decomposition, the structure of the numerator depends on the nature of the factor in the denominator.
