Graphical representation of the derivative of y = cosx

This example demonstrates how to graphically represent the derivative of y = cosx. It involves core math concepts like derivatives, cosine function graphs, and their rates of change. Constructed using GeoGebra commands/objects h and f for plotting the function and its derivative. Suitable for high school students learning calculus and the relationship between function graphs and their derivatives, aiding in understanding the geometric meaning of derivatives.
