I just woke up, and there are about 4 different people talking to me :/ Sorry if I didn't reply to anyone.
Has anyone ever heard of the term Diophantine equation? I looked through this book and it's pretty mind blowing stuff. E.g. for the equation 19x+83y=1983, in positive integers x and y are obviously given by [100,1]. There turns out to be exactly one more pair which satisfies the equation. What is the number pair? I wish I borrowed this book ('Problem Solving with the AMC') a long time ago.
On that note, I got 47/57, which makes me go T_T Sure, it might be a decent mark, but when your report was 71% and you want to get back above 80, it just doesn't cut it. Also, I heard the top class average was 55, but second class was 42.7, I swear our teacher said he would make it easy. I made several human errors, and I could have easily gained at least 5 marks if I remembered my graphing properly...
In terms of weight, this is 20% (minus non-calc?), the half yearly was 25%, and the term 1 tests were worth 15%. Everything is riding on yearlies *mild panic sets in*
Gud nacht (?)
For some really really really strange reason, I randomly subbed 20 in and it worked. And I was like WOAH! (19 x 17 + 83 x 20)
