haha that stuffs a bitch, i always get the similar sides wrong n stuff, luckily i ddin't have that stuff in my test. my test was all equations, i was like omg wtf it was basically integration, differentiation and sequences etc there was no coordinate stuff or anything past band 3 q's so i...

From the original bag of ten marbles, 3 are drawn at the one time. Thses 3 are put into another bag and one marble is drwn without looking. What is the probability that this marble is white? 6c0.4c3/10c3 * 3/3 + 6c1.4c2/10c3 * 2/3 + 6c2.4c2/10c3 * 1/3 i think that is it 1/30 +...

sorry, my bad

(Integration sign)1-2 2x - 1/xsquared dx = S (2x/x^2 - 1/x^2) 1 - 2 = S ( 2/x - 1/x^2) 1 - 2 = (2ln(x) + 1/x) 1 - 2 = 2ln2 + 1/2 - (2ln1 + 1) = 0.8862

hey rama v, do u mind me asking what type of question u lost marks for? :D

thanks all, you people are so helpful :D:D oh, i *think* they are common rules, but none the less, my teacher is a nutcase, he'll put in any sorts of questions cause he's a gaybo. LOL thanks

Integrate: S(cosec^2(x))dx A = -cot(x) + c S(cosec(x)cot(x))dx A = -cosec(x) + c S(sec(x)tan(x))dx A = sec(x) + c These are common rules i think, but im pretty sure my teacher will put 1 of them in the halfy tomorrow!!! (unless these don't have to be proven? but i cannt be...

yeh but its funny tho, that's why i posted it i actualy repped him ages ago if i remember correctly, so its got a long memory which is pretty good lol ...but slide rule deserves the rep lol! he's so helpful :D

umm ask ur teacher what the weighting for the exam was (usually for half yearlies its 20%) so say u get 63%, that's 63% of 20% of ur internal assessment mark. that is 12.6%. so say if u get 100% in all ur assessments and 63% in this half yearly, then ur internal assessment will add up to 92.6%...
