Determine whether the following improper integrals are convergent or divergent. If the limit exists and is a finite number, we say the improper integral converges. Write the fraction using partial fraction decomposition. One of the most important applications of this concept is probability distributions because determining quantities like the cumulative distribution or expected value typically require integrals on infinite intervals. Multiply the numerator by the reciprocal of the denominator. Divide each term in by. Since both terms are perfect squares , factor using the difference of squares formula , where and. Cancel the common factor of. Replace all occurrences of with. Rewrite the expression. Decompose the fraction and multiply through by the common denominator. With Example 2. Simplify the left side. Step 2.
