Since when was Kondosan so smart in math?

I want to dominate the world...

You survived?

ah, no argument on that * Immediately thinks about "Elizabethchan" * 
Zura janai! Katsura da!

Wow, it's almost been a month since someone has been here... does anyone even use this room anymore???

Firelies~~ >o<


Sensei

It felt like yesterday when I was last here.........

Sensei

haha...i think i've been in here once.....

hmmmmm...i thought this is the math class so what are you guys talking about??
ok i have a question: can someone explain me why cos(x) is the derivative of sin(x) thanks

fi you mean why (x) becomes lower then try typing : shift +(cos/sin) + (x) then it become bigger
