Understanding the Derivative of e^x

The video explores the graph of y = e^x, highlighting the fascinating property that the slope of the tangent line at any point on the curve is equal to the value of the function at that point. This unique characteristic of the number e is discussed, emphasizing its magical nature in calculus. The video concludes by mentioning that a proof of this property will be provided in another video.
