Derivative as Slope Function by Sangeeta Gulati

This example demonstrates the geometric concept that the derivative of a function at a point is the slope of the tangent line at that point. It involves core math concepts like derivatives, tangent slopes, and function graphs. Constructed using GeoGebra commands/objects such as Point, Tangent, and Slope. Suitable for high school calculus instruction to visually understand the geometric meaning of derivatives.
