Hörsaal mit Geteilter Brainrot-Leinwand

A realistic photograph taken from audience seating in a dimly lit university lecture hall, viewing past the backs of the heads of three students in the foreground toward a large projector screen. The projector screen displays a split layout with three vertical panels: on the left, vertical [Subway Surfers gameplay] with a character running along train tracks collecting gold coins and an on-screen score of "001022"; in the center, an academic lecture slide titled "[9.3: Infinite Geometric Series]" containing the text: "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." with slide footer reading "[Dr. Larson]", "[Calculus II]", "11/14/2024", and "7 / 35"; on the right, vertical [Minecraft parkour gameplay] with floating wooden blocks above a grassy landscape and a TikTok watermark in the bottom corner. The lecture hall features an acoustic drop ceiling and chalkboards visible behind the edges of the screen.
