Integration by Parts: ln(x)^2

The video tutorial explains how to integrate ln(x)^2 using the integration by parts technique. It begins by introducing the integration by parts formula and setting up the problem by defining variables and using the chain rule. The tutorial then applies the integration by parts formula to solve the integral, followed by a second application of the technique for ln(x). Finally, the video concludes with the final solution and a summary of the process.
