Please help, this is very important.

Prove that

lim (x->inf) (sinx - sinx) = 0

lim(x->inf) (sinx - sinx) = lim (x->inf) (0) = 0

is this right?

I'm self-learning Japanese and am interested in beginning to learn Kanji, but I'm not sure what information I need to know about each word. I know there is a lot of information about each one: stroke order, kun and on readings, homophones, etc etc.

What do I need to know about each one to get a full understanding of Japanese/attain fluency? I don't want to cut any corners, but I also don't want to learn things I really don't need to know.

Thanks in advance!

The pencil graphite from my mechanical pencils falls on the floor and then gets ground into the tile by my chair. Is there any way to remove this gunk? It is pretty thick. I have tried windex but this removes it very very slowly. Please help, I will be charged a cleaning fee by my college if I cannot clean it!
