Final answer:
To find the partial fractions decomposition of an integrand, we need to break it down into a sum of simpler fractions. This method is useful for integrating rational functions. The decomposition depends on the factors in the denominator of the integrand.
Step-by-step explanation:
To find the partial fractions decomposition of an integrand, we need to break it down into a sum of simpler fractions. This method is useful for integrating rational functions. The decomposition depends on the factors in the denominator of the integrand. Let's say we have a fraction with a quadratic denominator, like (x^2 + 2x + 1). We can decompose it into two simpler fractions: A/(x + 1) + B/(x + 1)^2. The constant A and B can be found by equating the numerators and solving for the variables.
