Algebara or geometry depending on the problem?????
Interested in Language
Let say I have to prove A = B. I assume that A is not equal to B and I derive that this assumption violates a well-known statement, meaning that this assumption is not true. Therefore A must equal B ( It is proven).
My question: What is this method named?
Thanks in advance.
Algebara or geometry depending on the problem?????
My 10th grade math teacher would know this. I remember using this method to prove that the square root of 2 is irrational, by starting by assuming it was rational.
We need a math teacher to stop by.
I'd call it Logic or Logicism.
More suggestion please? Thanks.
