$\int\left(\frac{x^3}{x^4}+\frac{1}{x^4}\right)dx$

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. Simplify the resulting fractions. Expand the integral \int\left(x^{-1}+\frac{1}{x^4}\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int x^{-1}dx results in: \ln\left|x\right|.

 Final answer to the problem

$\ln\left|x\right|+\frac{1}{-3x^{3}}+C_0$
