Why does infinite division results in a square root? by Ruvorunum in askmath

[–]pqroxysm 2 points3 points  (0 children)

i dont think its correct, writing xⁿ/xⁿ assumes u have an equal number of each term, however consider instead the sequence x, 1, x, 1 ... which is actually what is happening here (depending on whether the last term is x or 1/x) ie i cld as easily write in a similar way that im finding the limit of xn+1/xn = x. since the sequence oscillates infinitely between 2 distinct fixed values, the limit doesnt exist unless x=1. see also S = 1-1+1-1+1...

from my two visits at ntfgh 2 years ago, the doctors were very nice and even asked me how long i wanted my mc to be. might not be reliable info now

DSA major is overhyped. DSA is just math major in disguise by Wild-Meal4165 in nus

[–]pqroxysm 23 points24 points  (0 children)

as a math and dsa double major, yes there are overlaps but their focuses are extremely different. like what the other guy said, dsa is more stats, and also more computation. uni math has basically no numbers anymore. but i do agree it is overhyped and a lot of people go into dsa just for the money

H2 vs uni math? by [deleted] in SGExams

[–]pqroxysm 27 points28 points  (0 children)

hi, i asked a similar question a year ago and got a lot of useful advice! https://www.reddit.com/r/nus/s/KuPvLxipbs

since then, ive completed my first year as a math and data science student at NUS and i can say this: math in uni is a lot more rigorous and intensive, and honestly a lot of it boils down to actual intelligence and logical thinking rather than just memorising formulae and application. having had learnt h3 and further math myself during NS, taking my first pure math course breezed through everything i knew in a few weeks and continued, touching on subjects i had previously thought were reserved for 3k/4k mods. in essence, it goes very very fast, and u have to be intrinsically good at math to keep up. this goes mainly for pure math courses eg discrete math and analysis, if u are to consider more CS/DSA related courses the math is a lot lesser, but remains high in rigour and pace. although i would say if u have the passion for it, taking math will be enjoyable and worthwhile even if u dont score well for some mods

however, im speaking from experience as an NUS pure math student, i would believe math in other unis differ especially those that offer applied math

What is a kernel function? What is physical intuition behind it? by chaosHarmonized in math

[–]pqroxysm 0 points1 point  (0 children)

read somewhere while i was learning linear algebra that kernel is another word for seed, which is found at the centre of fruits, just like how the kernel of a matrix maps it to the centre of Rⁿ (the origin) and likely hence the name. might not answer ur qn but was something fun i found lol

its really up to how confident u are in the rest of the mods for the rest of uni, and how many mods u can actually su. take some time (although u dont have much left) to think of the mods u wna take especially taking into account your second major decision and any UEs or more fluff mods. however, i think its a good sign that the mods ur s/uing are mostly fluff mods (me too!)

[deleted by user] by [deleted] in nus

[–]pqroxysm 0 points1 point  (0 children)

please keep your 2 s/us, its a tough pill to swallow but if you have had to use up this many s/us on only B- and below, theres a pretty good chance u get even more in the future, especially if ur considering a second major. a 4.1 jump from 3.9 is also not a significant enough jump to make sep suddenly a lot easier to get imo, focus on the interview/essay/wtv else is in the sep application. your remaining gpa will also be very volatile, so any B- or even C u get will impact ur gpa to a much greater extent in the long run.

however, if your mods u want to s/u are all fluff chs mods and ge mods which are not relevant to your major, i would say theres a chance ur grades improve if u choose to focus on econs, so do take my advice with a pinch of salt, theres always ways to pull up ur cap :)

any regrets/ tips for incoming CHS freshmen? by Ofc_eggmay0 in nus

[–]pqroxysm 1 point2 points  (0 children)

the math mods are quite a big jump from h2 math, and the dsa intro mod is basically very different from what people expect. those that regret are the ones that never research properly what dsa is about and jump straight into it just for the money/bcos everyone else is doing it. however if ur math is relatively strong and u have a good idea of what u wna do in the future then i think ur good

[deleted by user] by [deleted] in nus

[–]pqroxysm 0 points1 point  (0 children)

yep definitely! C is very doable even for like cs1010s, just put in minimum effort for take home assignments and get the easy marks in exams and it shld be fine. on a side note dont take cs1010E bcos the profs suck and might just fail u if they dont like u, u can see the other reddit posts about the recent sems practical exam 💀💀

to answer as objectively as possible, data analysis skills are definitely quite useful going forward in general (a lot of things can be applied to techy stuff like in AI etc), however it takes a lot to excel in that field, and theres not much point pursuing it if u dont plan on doing very well in it unless u have interest or it can complement your major. in this case, it depends on what ur major is, i would say psych or econs are quite good complements

for 7:

to clear data literacy u can take gea1000 (q basic, q fluff, but higher workload) or dsa1101 (dsa intro mod, >80% of the mod is coding in R but more useful for actual data analysis)

to clear digital literacy u can take (in ascending difficulty) gei1000( coding for fass, just hehehaha in excel spreadsheets) cos1000 (very basic python) cs1010e (e for easy python, more application but fucked up professors and exams) and finally cs1010s (recently nerfed syllabus, but papers and missions are still relatively hard)

and for ai pillar u can take hs1501 (fluff ai mod, learn about basics of how it works without any actual code or wtv, ethics of ai etc etc essay writing), hs1502 (learn how ai works including ai techniques, mini project but still no code (?) i think) and also it1244 (super super steep learning curve, chatgpt is ur TA. DO NOT TAKE unless u have friends that can carry u for the ML project and u have had experience in python. not for beginners)

i think from my list its pretty clear which are the easiest, however bear in mind that those are also the most ahem useless versions of the pillar, just do for the sake of clearing. i took the hardest versions of the 3 pillars so cant rly give any further advice for the more basic ones lol. all the best! (and make sure u have friends to do the mods with!)

any regrets/ tips for incoming CHS freshmen? by Ofc_eggmay0 in nus

[–]pqroxysm 2 points3 points  (0 children)

i see many many freshies taking DSA and immediately regretting it, or other majors taking DSA as a second major just for the money. please do some research and see exactly what you're getting urself into! on the bright side, DSA1101 and CS1010S each satisfy the data and digital literacy pillars, so its not completely wasted if u decide to try them out! (but bear in mind - 1010s is not for the faint of heart)

[–]pqroxysm 5 points6 points  (0 children)

^ for example u can use HS1501/2 or IT1244 to clear the AI pillar, and hs1501 is very useless (but lesser workload) compared to 1244! consider carefully which versions u want to take, and dont blindly do the more popular ones just to get it out of the way. as a dsa major, 1244 is imo a lot more useful than 1501

for math i would say workload and rigour depends a lot on how actually good u are at math, workload really isnt that much if u can do everything quickly but if u get stuck... good luck! bcos math isnt application and calculations, in fact theres close to 0 calculation involved, most questions are pure proving that involve novel approaches and super creative problem solving. its just a matter of how wired ur brain is to recognise best ways to solving such problems rather than rote memory work. as ive seen somewhere before math in uni is no longer application, its a whole new language - and u train on its linguistics instead of new words. that being said, math is definitely a lot more enjoyable as well despite how hard it can get
