bad poetry.

procrastination

tomorrow, and tomorrow, and tomorrow,
and tomorrow and the day after that too,
im putting off studying- phys, chem and bio,
and when exams come i'll say time has flew...

its not like maths is that complicated,
its not that econs is all greek to me,
its just the fact that im unmotivated,
unlike most other students i see...

but when the exams loom alarmingly close
ill sit down and cram, and hope for the most

mmm... another stressouted poem by the your sg alevels student.

eve.

                            

Geek(ish) Graphic Calc Stuff

And so, i was getting bored - actually, it was me and Chew... and i guess we were both bored. or something.

Anyway, i decided to explore my TI-84 Plus Graphing Calculator. Inexplicably, i had this urge to program - yes, on my GC, no, not using any other interface but the GC keypad - a cross product function.

Somehow or other, Chew got dragged into it =P

It works, sorta, for all rational numbers between -999 and 999.

Here's the program (i take credit for about half of it. lol)

:ClrHome
:Output(8,1,"CROSS PRODUCT")
:Prompt I,J,K,L,M,N
:ClrHome
:Disp JN-KM => Frac
:Disp LK-IN => Frac
:Disp IM-JK => Frac
:Fix 2
:Output(5,1,I
:Output(5,9,L
:Output(6,1,J
:Output(6,8,*
:Output(6,9,M
:Output(7,1,K
:Output(7,9,N
:Float

It doesnt seem right, tho, that the manipulation of the Display Screen (all the Output lines), take up way more space than the actual calculations....

But what the heck, it works. =D
Just don't get it to manipulate irrational numbers (like pi).
Or those that are too large.
[ Well, it *can*, just not accurately.]

eve really should be studying more.

procastination season, again

but its not *really* my fault -- what kinda normal person'll be able to study at home after reaching home from school at 7++ pm?

oh right, just about every singapore jc2 student.

so im not alone, and that makes me feel so much better. really, it does. really. (and if i keep repeating this to myself maybe, just maybe, i'll act like i believe it, eventually)

i seem to be repeating myself very often. signs of long-term-minor-sleep-deprivation.... long term as in 3 weeks or so. minor as in between 5-7 hours of sleep per day, minor cuz its just a lack of 1/2 hours per day.

it adds up. i think.

it doesn't matter anyhow. for some odd unknown reason, i can't sleep even when i need it and i actually have 4 to 5 hours to myself without any pressing issues. like now. sunday morning. perfect for sleeping in --> all the way untill 1.45 pm. cuz lunch is only served till 2.

and what am i doing? im blogging. go me.

plus, im skirting the major problem. the very very very majorly panic inducing ones. E.X.A.M.S.

the only subject im going to rant about here now is the one i don't have much of an issue with. GP.

it looks like after one and a half years of "learning" it, my marks are stagnant. stable enough that all, and i mean all, my exams marks is within a range of four percent(60 - 64). which is annoying.

i have come to the conclusion that the only semi-useful thing i have learnt from AJC's GP teaching methods is this : how to complete gp homework, by which i mean essays and comprehension exercises including summary and AQ, in short amounts of time.

i.e starting and finishing a complete essay in 45 minutes - 2 half-hour breaks, minus 15 minutes "rest" - or a comprehension paper within the same amount of time.

i never mentioned the quality of the homework, which is just about as lousy as you can imagine. i suppose i have just about given up on GP, its not like there makes a difference wheter i get a high B or a low one in A levels proper, a B is still a B.

and an A seems is impossible.

on that (relatively) cheerful note, i shall end this post.
