Integration Techniques and U Substitution

The video tutorial explains how to solve an integral using a formula from a calculus textbook. It involves performing a U substitution where U squared equals X to the fourth and A squared equals 16. The integral is rewritten to match the formula, and differential substitution is used to simplify the expression. The final integration is performed, resulting in a solution involving a natural logarithm and a constant of integration.
