Not him, but it's definitely overused when people first start learning proofs.

What does overused even mean? If it leads you to the correct answer who cares? Is direct proof also overused because it’s common?

>> No.12277516

>>12277500
It's often used in situations where a direct or contrapositive proof would provide a simpler, easier to follow approach.

i'm in college and can't do high school level math.

Personally I think uniqueness proofs are easier to follow when they're written by contradiction. When you suppose that some x1 and x2 satisfy a given property, most people are inclined to think of them as distinct objects since their representations are distinct. So you might as well just say they're distinct and make it a proof by contradiction.
