摘要
运用GeoGebra3D探究圆锥侧面的参数方程,结合圆面旋转的参数方程得出圆锥侧面展开图的一种方法,最终在GeoGebra3D绘图区完成制图过程。在此基础之上,推广到正棱锥的侧面展开图的绘制。
Using GeoGebra3D explore the parametric equation of the flank of the cone, the expansion graph of fl ank of the cone is gained with the torus of the parametric equation of a method, eventually in the plot area of the GeoGebra3D completed mapping process. On this basis, promotion to the expansion or the side of the pyramid diagram drawing.
