oh goody. just solved it. i wrote sin^2(x) as sin^3(x). -_- world is beautiful again... !!

i'm going to whine again. for the past 2 hours or so i've been stuck at a stupid maths problem (oh ya my maths final exam is tomorrow.) and until now i can't get the right answer. i'll list down the mistakes i've made in ONE SINGLE QUESTION so far: 1) used wrong formula right from the start 2) when discovered mistake, used incomplete right formula 3) integrate instead of differentiate 4) mistook sin^3(x) + cos^3(x)=1 5) mistook a-(-a) = 0 6) mistook -(0-(-a))=a 7) sub x=0 into equation, assumed (1 + sin (x)) = 0 8) differentiated (1-(x^2)) and i got 2x 9) integrate 2x and i got ((x^2)/2) 10) wrote f(x) + 2 as x+2 11) mistook 1/(sec x) for sec x!!! c'mon man! 1/1/cos x!!!! WTF!!! and until now my answer is still different from the actual answer and i don't know what other fucking mistakes still occur in my workings. despite writing step by step in my bestest handwriting ever i can still make mistakes. despite saying out the equation out loud "f(x) + 2 ", i can actually calculate as "x+2". and to make things worse, i consulted edison about a part of the question and turned out that the number they give is wrong! and i spent 0.5 hr at that part, thinking it's MY mistake. and in such a situation it has become a personal vendetta it is hard to just give it up. my maths SUCKS period. i can really crush my notes right here right now! ccb

do diamond water filters really work? just curious.. my neighbour has been having free samples of water filtered by so-called "diamond filters", and in all her good intentions she also has been offering my family bottles of such water for consumption. according to the company this water can detoxify the body and cures ailments in a few days. the catch: the filter itself costs $1700. i went online to do some research and found several sites proclaiming their "diamond filtered" water is the cleanest water around. unfortunately sweeping statements like "Water cures depression, loss of libido, chronic fatigue syndrome, lupus, multiple sclerosis, muscular dystrophy." actually kills much of the credibility it had initially. i mean, it's undeniable that bacteriostatic water is healthier to some degree but that claim is seriously exaggeration. and there are several other statements like that, all from various "diamond filter" companies. one even claims that the water is so odourless (hence pleasant to drink) will encourage everyone to drink more! -_- end verdict: not worth the cost. (i hope i'm wrong though... the persistent sinus/flu/excess cerumen/excessive dry eyes have been irritating me for days. ) aight.. back to study. final exam in um.. 11 hours time. and i just watched 4 episodes of friends... this out-of-point article is the result of ultimate boredom.

i think i might have injured my ear. i have been experiencing this occasional throbbing pain in my ear ever since a few days back where i inserted a cotton swab too deep in resulting in some bleeding. then, if it isn't painful, it is very itchy, and i can't help but press of the lobe against my ear repeatedly. and then leads to the pain cycle AGAIN. and pus (not wax) seeps out once in a while. and of all times, my piercing (same ear) has to get infected at this time! hopefully not a punctured tympanic membrane??? and hopefully not too much information too.. lol.

just watched nip / tuck on tv after missing the whole of season 2... nip/tuck is a series about two plastic surgeons, and their messed up lives and families. and it is quite frustrating when no one bothers to put in the effort to work things out. and the storyline just gets wilder and wilder. boy. is this the opposite of reality tv or what? in one episode, we have: the docs performing a plastic surgery on a ...gorilla?!?! one of the docs performed an operation on a transexual who happened to be the lover of his son, and not wanting to tell his son about it for fear of hurting him?!?! the son's mom and grandmother smoking pot together, having a casual conversation?!?! and believe it or not, there are even more wilder stuff that i refuse to post. it is one thing to push the boundaries, another to do it at the expense of the credibility of the storyline. which idiot watches this bullshit? damn .. still got one more week before the next episode. damn.. five more days before exam season begins!!

sianz... my practical screwed up big time. argh there was this line where i keyed in "z<=9" but it should really be "z<9". and it made everything haywire. if i had been smart enough to change that everything will be perfect. super demoralised now.

some interesting programming thing i stumbled upon ... look for any websites with lots of pictures (www.soccernet.co.uk .. en.wikipedia.org comes to mind..) and paste the following to your address bar in your web browser. remember to wait til everything is loaded! it works for this page too! and it works differently for firefox and internet explorer! (i think internet explorer's one is more interesting.) javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.getElementsByTagName( "img" ); DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+ "px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+" px"}R++}setInterval('A()',5); void( 0); nice right!!

oh i'm pretty sure i'm going to fail my programming. pardon me but... FUCK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! argh. spent the last 6 hours doing a lab question that is supposed to be completed within 1 hr 45 minutes!! and even so it's not fucking complete YET! my head is going to BURST i SWEAR. it's like. after concluding that everything should be fine, you press the enter key and write the program... only to be greeted with a sudden influx of 100 lines of errors. your mood is totally TOTALLY gone. but you still gotta continue and find out what the fuck went wrong. ARGH. fuck i feel like a bloody idiot. changing variables here and there and still getting the same old mistakes. i just can't grasp it!! and practical exam is in 2 weeks time!!!
