T.T ytd physics test. argh. no time finish. maybe i waste too much time thinking of wad to write. and ppls is nvr finish back, but i nvr finish front. cos of my bad habit of doing things frm the back xD!
NOOO, i TOTALLY HATE TRIGO man. main culprit -> ms siew! ARGH! NOOOO! my trigo alreadi very cham le, for every exam paper got trigo sure arrow me de. DEN! today recess, i was reading newspaper at classroom, and she randomly came towards me, and ask me, "What is 1/sin?" lol! stunned and im dead, and she said she want me to be out of the classroom during her period until i memorise all the formulas. T.T
though it is only half a period, 20mins it is like hell, and 2 teachers walked past me while i was standing outside, one screw me, one show bit of concern. LOL. so embarrassing la. and nw i am 100% sure dat i can read out all the formulas in 10 secs. KAO.
sin^2 + cos^2 =1 1+cot^2 = cosec^2 1+tan^2 = sec^2 1/sin = cosec 1/cos = sec 1/tan = cot sin/cos = tan sin(90-0) = cos (90-0) tan(90-0) = cot (90-0)
HATE U TRIGO!
