Relationship between Definite Integral and Area

This example explores the relationship between the definite integral and the area bounded by f(x) and the x-axis on [a,b], helping students understand the geometric meaning of definite integrals. Key mathematical concepts include definite integrals, function graphs, and coordinate geometry. Using GeoGebra commands such as Integral and Area, students can visually observe the connection between definite integrals and areas.
