Section 25 due November 7
1. I like these definitions. The proofs are pretty straightforward. Questions... I don't know if I have any questions. Is the image to a function as an equivalence class is to a relation? Am I understanding that correctly? Like it's the set of outputs?
2. This would have been helpful at the beginning of Linear Algebra. Holy cow, this makes one-to-one and onto seem way more simple than we were making them in that class. But I guess the order we've learned them in hasn't been too bad. Honestly, I think it would be good to learn mathematics the way we do in this class starting way younger. Like, if I had started this in 9th grade or somewhere around there I think that I'd have a much easier time learning and becoming fluent in the language of math. Just a thought.
