A story about dy/dx

At the end of last year,
in the 2nd semester,
in a class of additional mathematics,
the last chapter which is Differentation.
I didn't come to school when my teacher introduces the chapter to others.
I was absent on that day because I didn't finish my chemistry homework.
hee :)
and silly me, I forget about the time table changes.
grrr..
unfortunately, there was no chemistry class on the day I didn't come.
what a dork ..
back to my story,
when I came back from my 'pleasure holiday' and attend the additional mathematics class,
I was LOST.

totaly lost.
I don't know what the heck was my teacher tought about.
it's like entering a japanesse class.
I don't understand anything she said.
while figuring out the formula that already wrriten on the board,
a friend of my ask;

FRIEND   : Asha, aku tak faham laa. Macam mana jawapan ckgu ngn aku tak sama ?
ME         : Entah. Aku pun tak sure. kejap aku tnya ckgu.

Then I got up and walked towards my teacher.

ME          : Cikgu, macam mna ckgu boley dapat jawapan ni ? tak sama la dgn jawapan
                 saya.
TEACHER : Apa yg tak sama nya ? Jalan kerja awak betul tak ?
ME          : Hm, perlu ke nombor 3 ni letak kat atas, kalau tak letak, bahagi ea jdnya ?
TEACHER : Ye laa. Sbb tu saya suro YOUALL convert dlu number ni.
ME          : Oh, mcm tuh. Hbis tuh, apa function 'dy' ni ?
TEACHER : Laa kn saya dah ajar semalam. Awak..
ME          : Saya tak...
TEACHER : ...da lupa ke ? Mcam contoh yang saya da bg tu la. bla bla bla...
ME          : owhh, saya pham. saya pham. trima kasih ckgu !

So , I went back to my seat and try to solve the equation. Then, my friend ask,

FRIEND   : So, mcm mne Asha ?
ME         : Entah la weh, aku pun tak pham...
