【2026年東大数学】理系第6問の整数問題、数学科首席が自信満々に間違える動画

-------Summary------- I attempted to solve Question 6 (an integer problem) from the 2026 University of Tokyo Science Stream Mathematics Exam. I started the explanation with a smug look on my face, thinking, "As the top student in the mathematics department, this should be easy," but my logic is completely flawed. Why, why, why, why? Please, all you brilliant people, laugh at me and point out where I made a fatal mistake.    • 【激難化】東大理系数学2023がヤバすぎる。数学科首席が本気で解いてみた結果      • 【難問】「sin1は有理数か？」数学系YouTuberのサムネに釣られて解いたら大敗北した      • 2024東大理系数学と京大数学のヤバすぎる整数問題を解こうとした配信   --Tonsuke's Profile-- Junior High School: Hardcore online gamer (20,000 hours of play) High School: Public high school with a low academic ranking (deviation score of 43), repeatedly failing English University: Graduated at the top of his class from Ritsumeikan University, Department of Mathematical Sciences Graduate School: University of Washington Graduate School (Probability Specialist) 　　　　Withdrew after developing depression and being diagnosed with a rare disease Currently: Active staff data scientist (manager) / business consultant 📩 For work inquiries and consultations Please feel free to contact me by email for the following requests and consultations!
