Haha dw I became active on BoS during my HSC exams lol rip whatever studying I was planning on doing that monthenglish adv half-yearlies in less than 9 hours and i made a bos account instead of starting to study gg lmao
hi idk how this works but hi(?? ?)
Just differentiate the geometric series a few times.You can't evaluate the second one by inspection or simple things alone so to speak. There's a really famous proof to it though.
Yes lol. Just cause it's famous doesn't mean it has to be complicated.Just differentiate the geometric series a few times.
Or was that what you were referring to by "famous proof"?
I just thought I'd ask because you said you can't evaluate the second one by "simple things alone". Surely the geometric series and knowing how to differentiate rational functions are pretty simple things!Yes lol. Just cause it's famous doesn't mean it has to be complicated.
But the first time you see it most people would forget to combine the methods togetherI just thought I'd ask because you said you can't evaluate the second one by "simple things alone". Surely the geometric series and knowing how to differentiate rational functions are pretty simple things!
Idk, some series/integrals have to be evaluated in super counterintuitive ways, but I wouldn't consider this to be one of them. It has a pretty clear visual similarity to the geometric series, and differentiation of the geometric series is used plenty of times in MX2 questions.But the first time you see it most people would forget to combine the methods together

Will have a look when I have time if you really want, don't have any high school books with me and don't have time to look through past papers right now.When was k.cos(kx) mentioned? I don't have any memories of this one...
this will be you next week.Half yearlies start next Friday RIP me
Lmaaoo where is the lie?? Haven't even started studying yet :')this will be you next week.
Same :')Lmaaoo where is the lie?? Haven't even started studying yet :')
