The video tutorial explains the concept of derivatives, focusing on evaluating the derivative of a function at a specific point. It begins with a discussion on the definition of derivatives and how they differ from finding the derivative of a function. The instructor then demonstrates how to calculate the derivative of a function, specifically using the example of F(x) = X^(1/2). The tutorial concludes by evaluating the derivative at a given point, illustrating the process with the example of finding the derivative at x = 9, resulting in a value of 1/3.
