How to Integrate Using U-Substitution | Integrate x^3/(x^4-5)dx

In this short video of CALCULUS we learn step by step! how to integrate functions using U-Substitution method.The first step in U Substitution method is to choose u and then find the derivative of u to get du and solve it for dx. After replacing the integrand with u , find the Integral ( anti-derivative ) and substitute back in terms of x.
