$\int\left(\frac{x^3}{x^4}+\frac{1}{x^4}\right)dx$
Learn how to solve integrals of rational functions problems step by step online. Find the integral int((x^3+1)/(x^4))dx. Expand the fraction \frac{x^3+1}{x^4} into 2 simpler fractions with common denominator x^4. Simplifying. The integral \int\frac{1}{x}dx results in: \ln\left(x\right). The integral \int\frac{1}{x^4}dx results in: \frac{1}{-3x^{3}}.
Final Answer
$\ln\left(x\right)+\frac{1}{-3x^{3}}+C_0$
