Woke up at about 1pm today, after a happy dream which made me wake up smiling.
Brush teeth and took out laptop and went to see blog as my first routine as usual.
Then see le sian diao and feel sad and glum.

At about 12+am i was dotA-ing once again.
Then later quitted.
I not pushing the blame, just saying why no reply..;c
This was my chat hist to prove what i saw, so maybe its jsut my internet's prob..


Well..just studied trigo..which was last year topic which i din't listen.
So..to summarise what i have learnt just now..based on my memory..

secx=1/cosx
cosecx=1/sinx
cotx=1/tanx
tanx=sinx/cosx
sin²x+cos²=1
sin²x=1-cos²x
cos²x=1-sin^x
cotx=cosx/sinx
1+cot²x=coses²x
1+tan²x=sec²x !!!

AHHHH this topic is so intimidating..T_T
