Sal continues where he left off with the last video, "Derivatives 1, Ó by looking at the equation y = x2 and examining the slope of the second line at a specific point. He continues defining the limit as x approaches zero to get the slope of the tangent line (derivative to the curve) at a specific point. In the following Khan Academy video, "Derivatives 2.5, Ó he will generalize this technique to find the general formula for the slope at any point.
