next time if you are on the mrt, dun start staring at some random guy with a big bag and start imagining his a terriost, go dig up ur memories and try to fit them together, i did that today and i somehow juz started find out a lot of stuff...... like wat is gradient, you see i kinds was distracted by sth last year during geometry class and happened to miss the definition, nvr was able to find out the excat definition again, untill today i thought on the bus that it is how many points y will increase for every one point of x, therefore the steepper the line the higher the gradient, vertical line has undefinied gradient, speaks for itself, not gonna think about it.
so therefore i decided to say that in physics, though you shld rely on definitions, you can try to explain with them if you really dun get it. so on a graph of velocity vs time, the gradient is for every 1 sec how much does velocity increases, which is accleration, dam, that was buggin me for days......
theres another one about orbits, not gonna explain, gonna spend more time on the bus tmr.....
"The kitchen tiles are your boxes, so your kitchen floor is your graph paper." - Physics teacher Mr Tien on plotting the position of how a cockcroach moves.
Speaking of that after 4 failed tries and 2 emails to the teacher i found that i hav typed the same thing wrongly into the calculator 4 times, thus resulting sth that bugged me for 2 days for nth, damit, at least now i got the right answer...........
