thank you for giving me the honour to post this post. because, believe it or not, this is post number 100! yeah! we have 100 posts on this blog already woo-hoo!
this shall be a speacial post, cos i'll reveal the answers to my three lame questions. hehe.
ANSWER KEY
Q1: simplify (x-a)(x-b)(x-c)... ... (x-z) as far as possible.
in the last third term there is a term (x-x)
(x-x) = 0
since the term is multiplication the whole expression now becomes zero.
i'll put qn 3 up first. hehe.
Q3: simplify sin x divided by n into a whole number.
the terms sinx and n have a common letter - n. since it's division, the two "n"s cancel and what is left is six. the whole number left is therefore 6.
Q2: why is the letter "O" always positive?
how do you write "laughing out loud" in msn language? "lol" rite? that is putting a mod sign on the letter O. therefore O is always positive.
funny? haha.
do remember to tell our classmates to visit class blog for details of class outing yea.
another joke:
have you heard of the butter joke? don't spread it.
