ohh ok thanks, i sort of get it, i'll have a closer look when i get back to insertion sort guess what i noticed, we both do ancient history and software X_X" got them two test on the same day lol SIGH atleast im not alone

hmm yeh tracing it out helps heaps, i know exactly how each sort is different and what they do, but with this sort i dont understand WHILE ShuffleItem > Comparison Item(shuffleItem) = Item(shuffleItem - 1) Subtract 1 from ShuffleItem ENDWHILE whats (shuffleitem - 1) and then.. subtract 1 from...

yeh i got excel too lol, but i reckon sam davis one is easier to understand, which i still dont understand, and its much easier to remember it when you do understand it, damn shuffle part :burn:

how do u find the range of x (cos^1) x to be -pi <= y < pi/2 if cos^1 x has range of 0 <= y <= pi x_x

lol sorry, i figured i shouldve put up the whole algorithm -.- yeah theres 3 loops altogether BEGIN InsertionSort NumItems = Number of items in list CurrentItem = 2 WHILE CurrentItem <= NumItems CurrentDataItem = Item(CurrentItem) Comparison = 1 Finish = False WHILE Comparison < CurrentItem AND...

>.> if only the software forum was half as active as the maths one lol sigh

the enhanced algorithm in the sam davis book... i dont really understand what's CurrentItem = 2 CurrentDataItem = Item(CurrentItem) how exactly are they related.. is the CurrentItem like the index.. and the CurrentDataItem the value of that index? =/ but what i really dont get is ths shuffle...

ohh thx i got it, it is -1/4, forgot to change 100/V to 100V^-1

well..its "According to Boyle's Law, the pressure of a gas is given by the formula P = k/V, where k is a constant and V is the volume of the gas. If k = 100 for a certain gas, find the rate of change in the pressure when V = 20"

P = k/V P = pressure k is constand and V is volume if k = 100 for a certain gas, fine the rate of change in the pressure when V = 20 *lost* =/

in ur dreams, only u dream about 2 guys, whenever ur not spyin on apes from across school that is, lmao

cant believe my simple 'integrate sin^2 x' topic lasted this long O.o"

but before couldnt we change our subjects without emailing admins, i remember ppl at school did it all the time, not too long ago as well

ya when my friend told me i got ancient and software on the same day i was like... yeh sureeee...but omg, sigh, + ext maths the day before = gg

October Friday 19th – English Friday 22nd – English Monday 29th – maths adv Wednesday 31st – maths ext 1 November Thursday 1st – ancient history, software Monday 5th - physics ancient + software...6 hrs x_x" and day before that got maths ext 1:burn:

x_x" ahhh my eyes T.T"

dude u need like 9 hrs sleep man, put school before health? good for u its already been proven heaps of times, go ask the people thats already gotten high uai's, alot of them dont study everyday, dont study more than 5hrs a day not counting school time and spend more time with their gf than...

lol sin (x*pi/90) >.>" close enough i just got lazy hahah anyway thanks for the help :) i dont need to know any of this 'integration by parts' for ext 1 do i? o.O"

i do know radians lol sort of answer is 1/2 (x - 90/pi sin (2x)degrees) + C ...=/ if i got sin pi/90 would that equal the sin 2x degrees and still be right

actually the actual question was integrate sin^2 x(degrees) lol and that changes to 180/pi or something (guessing) and i get a slightly different final answer than the book =/
