Do You REALLY Understand Derivative? | Symmetric Derivative and Generalized Pseudoderivative

You think you know the derivative? Think again. The classic definition, the limit of the forward difference quotient (or the backward), is only one way to define the slope of a tangent line. But what if we change the rules? In this video, we dive deep into the fascinating world of generalized difference quotients and pseudo-derivatives. We explore non-standard schemes like the +2h and -h difference, and the infamous symmetric derivative, and ask a simple but profound question: Why did Cauchy and the other math giants settle on the definition we use today?
