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

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

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
