脑腐课堂投影仪

提示词

一张逼真的照片，拍摄于昏暗照明的大学阶梯教室的观众席中，视角越过前景中三名学生后脑勺，望向一块大型投影屏幕。投影屏幕显示一个布局，分为三个明显的垂直面板。左侧面板显示纵向的 {argument name="left game" default="Subway Surfers gameplay"}，画面中一个角色在铁轨上奔跑，收集金币，并带有诸如“001022”分数之类的界面元素。宽大的中间面板显示一张学术演示幻灯片，标题为“{argument name="slide topic" default="9.3: Infinite Geometric Series"}”。幻灯片包含数学文本：“Example 3: Find the sum of the infinite geometric series. 1/3 - 1/9 + 1/27 - 1/81 + ... Solution: The series is geometric with a = 1/3 and r = -1/3. Since |r| < 1, the infinite geometric series converges. S = a / (1 - r) = (1/3) / (1 - (-1/3)) = (1/3) / (4/3) = 1/4. The sum of the series is 1/4.” 幻灯片页脚显示“{argument name="professor name" default="Dr. Larson"}”、“{argument name="course name" default="Calculus II"}”、“11/14/2024”和“7 / 35”。右侧面板显示纵向 {argument name="right game" default="Minecraft parkour gameplay"}，画面中木质方块漂浮在草地景观上方，右下角带有 TikTok 水印。房间有悬挂式天花板，屏幕边缘后方可见黑板。
