Easy way to find the derivative given the definition of derivative

The video tutorial explores the concept of limits and derivatives, focusing on understanding and applying the definition of a derivative. It explains how to calculate the derivative of a function using the limit definition, specifically for the function x^3 at a point where a equals 2. The tutorial emphasizes the importance of finding the slope of the tangent line at a given point and provides a step-by-step approach to solving derivative problems.
