True or false? $x^2\ne x\implies x\ne 1$ At least my classmates believed me. A few weeks later I learned that my teacher had been talking about this to his coworkers about this. One of my older math teachers congratulated me, said he hated the guy for some reason and that I was very unlucky to have him as my teacher. Anyway, math.stackexchange has been very helpful :) Thank you very much! |

True or false? $x^2\ne x\implies x\ne 1$ Yes, I went in the other day like a boss, with the proof you guys gave me presented on paper. He still didn't believe me. The next day, I emailed one of the writers of the book with my proof and asked him what the correct answer was. I was sure I was right already, but I felt I had to convince him. He called me right away, he was pretty impressed and said I was right. Next day I talked to my teacher about it after class (to avoid making him look bad in front of the class). Turns out the writer I called was his university professor. He still wasn't fully convinced, but he pretended to agree. |
