The Practice and Application of Visualized Experiential Teaching of Binary Function Calculus Based on GeoGebra

GoeGebra can organically link theoretical teaching with graphic demonstration, perfectly interpreting the mathematical idea of combining numbers and shapes, and presenting abstract mathematical concepts in visual graphics, achieving teaching effects that traditional teaching methods cannot achieve. This article is based on the Geogebra software to draw binary function graphics, compare the gradient direction of surfaces and the normal direction of tangent planes using graphics, and draw the volume graphics of curved top cylinders. These three applications demonstrate the powerful and convenient graphic drawing function of the software. Visual display can cultivate and enhance students' spatial imagination ability, help them understand and apply abstract concepts, further improve their core mathematical literacy, and effectively enhance the classroom teaching effectiveness of higher mathematics.
