SHM is quite simple i rekon the hardest for is binomial and probablity, and also application to the physical world i can never get these...

errr.. i hate binomial ... i wish there will be alot of trig as im quite confident at that :D

45 - 18 = 27

I used two PAGES for each question i could finish all questions in 5 booklets

i think 37.5 is still in 37th lesson, you shouldnt rounded it off

whats so hard about q1??

integrate and you will get [2x - x^2/8 - x^3/48]

integrate from -8 to 4, 2 - x/4 - x^2/16

I think i got 27 45-18 dont know if it is right or not atleast its a nice answer :p

I finishedQ1-9, double checked and left 1 hour and 20min to do Q10

arhh.... damn it.....i forgot to solve cos A i was like cancelling, dividng, multiplying and stuff, and i thought wtf, how do i cancel cosA to get the fina answer.... :vcross:

I couldnt get the very last question of Q10b can someone explain??

I found it way easier than last years at least Q9 and Q10 are

ln x + C ,,,,,,,,,,,,,

?? i dont think u can int (e^x)(x^2).. atleast not in 2u

if the question says answer in exact form, then leave it in exact form if the question does not say anything, both will be correct however, i found leaving in exact form is much easier

lol... no.. its ln x + 1 v' = 1/x

y'= lnx + 1 then sub in x

1,200,000 (1.005)^n = 8000 [1 (1.005)^n - 1 / 1.005 - 1] 150 (1.005)^n = 1 (1.005)^n - 1 / 0.005 3/4 (1.005)^n = (1.005)^n - 1 3/4 (1.005)^n - (1.005)^n = -1 -1/4 (1.005)^n = -1 (1.005)^n = 4
