I thought of polynomials, remainder theorem Think that's th only way, go learn that yourself with a good book

ooooooooooooooooooooooooooooooooooooooooooo k Soon there will be history in maths. History means essays. Essays means english, which then means every subject. Therefore Maths will soon then be/have everything Random post

^ lol Mudkip and "*In a bogan accent* Please explain? " makes you look so immature back then

Goodwin = Pierre? Confusion

Oh wow, I need to read all the thread first

Prelim ext trig is quite a considerable jump when I first did it. The proof(both algebraic and geometrical) was long

+1, I remem a question that just asked to differentiate x^x here

I had the last line expanded. It's quite long I'm not bothered showing full working here anymore...too tedious

lmao. 10% of my posts are in this thread

For c, I got a pretty long answer... I'm doubting it's accuracy since I did my working out on a paper that was already full of working out. I'm pretty this method is correct let y=x^x^x Let u=x^x Take ln on both sides and use implicit differentiation. I doubt this is a mathematics level...

yea...noone answered my questions too here Make RHS into one fraction then simplify Use the show part, integrate and use log laws to simplify the answer to 0.5ln[(e+1)^2/e^2+1]

ok What uni maths is that?

Try t=tanx, if that's not cool, expand the cos2x to it's trig(x) parts

Holy shit wtf lol

I think this is off topic for hsc maths for some reason From what I've read, logax=y a needs to be positive, thus x needs to be positive What about equations like these \(-a)^y = x where a is positive. x and y can be either negative or positive. I've done \(-1)^y(a)^y = x...

burned/owned

So...derivative= annagirl annagirl I think is banned, hence derivative is banned. Failed equations BTW why is this thread so long? Should've ended ages ago

He did, correct

Actually hard stuff What's the success rate of 90+ X2 students doing these questions?

OMG man I'm going to get 99.95, damn I have to work harder if I want to get into my course /mental dialogue within a person that gets estimated
