Perspective of 'Annunciation'

This example demonstrates the geometric construction and visual effect of perspective projection in three-dimensional space. It involves core mathematical concepts such as variance, exponential functions, random experiments, cones, and algebra. The construction uses GeoGebra commands like Ray and Segment, along with objects A, B, VP, f, C, g, D, h, E, i, F, j, G, k, H, l. It is suitable for high school and above students to understand the interaction between spatial geometry and function graphs.
