(tanx + cotx - 1)(sinx + cosx) =(sinx\cosx+cosx\sinx-1)(sinx+cosx) =(sin²x\cosx+sinx+cosx+cos²x\sinx-sinx-cosx) =(secx\cosec²x+cosecx\sec²x)

i rekon physics is just rote learning, there's only 4 topics and if u spend a few hours a day for a week u can pretty much cram the whole course in ye head:)

Bring forth an example and we'll try!!:p

"Today 10:04 PM yrtherenonames A primitive of lnx is x(lnx-1) The derivative of a log function is 1/x, if you're using base 'e', and if not, use the change of base laws to put it in base 'e' "

int. ln x dx let u=lnx and dv\dx=1 du\dx=1\x and v=x hence int. lnx dx=xlnx-int. x\x dx.......

Use integration by parts. let u=the log function and dv\dx=1

key thing to have is 'In the Wild' ---> the way in which humanity is linked with the natural world and their interactions

lol, but I like it ^_^

The number x and the real number @ are such that x+1\x=2cos@. Use Mathematical Induction to show that x^n+1\x^n=2cosn@ for all positive integers n>=2

10Ck\10C(k-1) =10!\k!(10-k)! * (k-1)!(10-(k-1))!\10! =(k-1)!(10-k+1)!\k!(10-k)! =(10-k+1)\k =(11-k)\k

ok, just asking. I never said there was a problem, so please don't get emotional:)

Are there all sorts of different people there? like are there many asians? or japs? etc..
