=.=, typing in LaTEX is long

this if your not sure about the -2sin^{2}2x + 1 cos4x let 2x=A so it will be -2sin^{2}A + 1 now; cos2A = cos^{2}A - sin^{2}A cos2A = 1 - 2sin^{2}A 2sin^{2}A = 1 - cos2A subbing A = 2x back in 2sin^{2}2x = 1-cos4x \therefore -2sin^2 2x=-1+cos4x \int (-2sin^2 2x +1)dx \int (-1+cos4x +1)...

:( i got sin4x/4

mey i ask what was the answer (from the book)

hmm, i would start it by turning 8cos^4 x into 8cos^2 x cos^2 x [which you can turn one of the cos^2 x into 1-sin^2 x] and then if you expand that out, the -8cox^2 x should cancel out

ooooo, nice, pretty sounds ;)

concentrate in class, finish your hw everynight (try to finish all of the homework you revceive) if homework has taken <1 hr, try study for 2 hours (go ahead if you know everything) if homwork has taken 1-3 hrs, study for about 1-2 hours (depending if you feel like you are behind) and if hw has...

don't study your ass of in yr 11, make it steady and with a good amount of free time, because at this rate, you'll burn out

outdoors in your backyard or something

year 10 was prob the most easiest of all yrs, even yrs 7,8 and 9 were harder than yr 10

this and also, try find a better way of studying (if you find your method now ineffective)
