should i continue learning year 12 content (1 Viewer)

[pl4smaa21]

yeah probably in 4u maths i do, but tbh english is really dragging me down - i think i'm average at best, and i also dont think i can study it early lmao

yea english is the BANE of every math student's existence

 

[pl4smaa21]

I aint doubting you alright don't get the wrong idea here but can u try to solve this problem if you can I got it from a 4U textbook

yeah true, also i have high functioning autism (diagnosed very recently) so that might be why im kinda bad at communications and stuff but good with patterns in maths... its honestly just a theory tho and also im pretty sure my condition is mild

yeah no worries i might just speak it out rather than writing the whole thing bc i cant be asked

a) Use integration by parts, with one of the parts being x^n u and the other term being v' (the mentality here is that we want to reduce the power of n to n-1 using differentiation so that we can achieve the T_n-1 which is specified in the question. this should evaluate nicely (this is a standard q im pretty sure)

b) we can evaluate T_0 (simple reverse chain rule). then sub n=1 into (a) and then we get T_1 and then we sub that back in recursively and we go up to T_3

c) apply the formula recursively so basically just use the rule on T_n-1 in part (a) and then again on T_n-2 and so on until u get to T_0 which u know and can sub in (i know that explanation was a bit weird so lemme know if u need more)

waaw u seem to know ur stuff d/w i understood it a bit like you I did also teach myself a bit of calculus

yep that's right

 

[joeystarbank]

oh nice! lol self teaching is defo the way to go with maths

 

[v.tex]

Imagine this is rage bait.

Although i think i believe it

thnx although I never went to the extent you did (lack of discipline) so props to you

Me 2 i believe it even though it is a bit unbelievable it definitely isn't impossible like for example look at terrence tao man learnt calculus at like 5 or some shit

ragebait even tho people like these exist -> weiwei

What’s sus is this guy commented on a Uni post about lectures..

 

[MoeyNeeds90+]

Hi so basically I'm in Year 8 for high school and since it's the holidays I don't really have anything much to do (I have already done all of the past papers that our school has given us which is ezzz). Do you guys think that I should continue learning yr 12 content?

Basically its guaranteed that i will be doing 4u maths, physics, chemistry, english advanced (idc what ppl say, im not gonna change lol)

for 4u maths i have already completed mechanics and integration (i found those quite easy).

do you think that I should be doing something similar for the sciences? pls give me advice current yr 12 students or graduates

(p.s. im aiming for a 99.95 atar to flex on my cousin lol. also SUBSCRIBE TO MY YOUTUBE CHANNEL called PokeBuddy12. im trying to make at least $10,000 dollars off it so i can buy a new gaming pc cuz my dad says its too expensive lol but i wanna prove him wrong)

lol i was just kidding if u look at my post i said the lecture got removed which obviously isnt the case

so according to the internet ragebait is when i post something that causes anger... what did i post that makes u angry??? i just wanna know if its possible for me to start learning yr 12 physics or chemistry right now...
