Learn how to find the points of inflection for an equation

The video tutorial covers the concepts of concavity and inflection points in calculus. It begins with an introduction to these concepts and proceeds to explain how to find the second derivative of a function. The tutorial discusses different methods for simplifying the derivative, including the power rule and chain rule. It then analyzes the second derivative to identify potential inflection points and sets up a table to test for concavity. The video concludes with a summary of the findings, emphasizing the importance of understanding concavity and inflection points in calculus.
