I challenge you plebs to prove this infinite sum

I challenge you plebs to prove this infinite sum

trivial

Left as an exercise to the newfriends

weak bait

I'll start the proof.

Towards a contradiction, suppose that the statement is untrue.

That's not how it works friendo

You can't start a proof by saying it's not true dumbass you have to show it first

let me guess, all you know is "HURR DURR PEDMAS" from high school and you think it's the golden rule for everything

Idk how you are supposed to prove this, but you can do it via the Fourier series of x, x^2, and x^3.

just sum all up and see if they equal each other
