What's a Derivative ? Differentiation ? The Gradient Function - Slope of a Curve
What’s a derivative? What’s differentiation? In this video I introduce the derivative function by showing how it is used to calculate the gradient, or slope, of a curve at any point along its length. We see that the gradient of a curve at a point is defined as the gradient of its tangent line at that point.
