Whoever added the citation needed got more of a laugh out of me then Randall did this morning. Well done. --[[Special:Contributions/172.68.142.29|172.68.142.29]] 17:32, 28 June 2017 (UTC) | Whoever added the citation needed got more of a laugh out of me then Randall did this morning.

:: Unless I'm way off-base, There are an infinite number of solutions. For example, let's assume f(x)=2x and G(x)=x+1. X can, in this example, be literally any number because G(f(0)) = G(2*0) = G(0) = 0+1 = 1. As long as G(x) takes the result of f(0) and makes it equal to 1, it doesn't matter what f(x) is.

"I'm finally in the right one," made me laugh more than usual. It added character to Offscreen Student #2, something that the comic usually lacks [[User:HisHighestMinion|HisHighestMinion]] ([[User talk:HisHighestMinion|talk]]) 03:56, 29 June 2017 (UTC) | "I'm finally in the right one," made me laugh more than usual.

According to https://en.wikipedia.org/wiki/Constructive_proof "existence proof" means a non-constructive proof. Such proofs are annoying to some mathematicians as they claim existence of something but do not show how to find it. So I fully understand the teacher that she wants to grab a sword and finally find it.

To me, the comic reads (especially with the title text) with the implication that the teacher is encouraging the students to help her actually fight real numbers in real life, as if the platonic idea of numbers was "realer" than we think.
