the .9~ = 1 is easy to prove with some basic algebra .9~ = x so 10* each is 9.9~ = 10x minus the original equation leaves 9 = 9x so x is 1

I dot think they are the same or they would look the same they might be equivalent but it's like saying "4 is actually just 2+2"

echinopsis posted:I dot think they are the same or they would look the same they don't have to look the same to be the same number. 2/3 is the same as .666..., just as 3/3 = .999... = 1. also it is completely accurate to say that 2+2 and 4 are the same number, that's what the = between them means

I, in all my non knowledge, disagree I thought the whole 1/3 = 0.333 was allowed as an approximation but that 1/3 is a perfect 1/3 while 0.333 is merely a noble attempt it's like, you just cannot completely represent 1/3 as a decimal without compromise other day was wondering if square wave was really just a bunch of sine waves or if rather the square wave could be analysed as a bunch of sine waves but wasn't actually the same thing

echinopsis posted:I, in all my non knowledge, disagree .333 is not the same as 1/3 because the repeating 3s stop after a finite number of them. so yes that's just an approximation. the key is the ..., which means the 3s go on FOREVER. this ... notation is just shorthand for the sum of an infinite series

echinopsis posted:
A square wave is a non-sinusoidal periodic waveform (which can be represented as an infinite summation of sinusoidal waves), in which the amplitude alternates at a steady frequency between fixed minimum and maximum values, with the same duration at minimum and maximum. from the wikipedia article on square wave, which led me to this: https://en.wikipedia.org/wiki/Gibbs_phenomenon

you should go back to Gibbs

basically it's kind of a weird consequence of defining real numbers (which is intimately related to how you deal with infinite sums). you have no idea how bananas real numbers can be if you just throw away real numbers and try to assume 0.999... != 1 you still get a somewhat consistent system, but it's even crazier this is what mathematical definitions are all about, making choices that lead to the relatively most sensible systems
