The Sharp Mathematics Contest #2
Stop Press!
Are your eyes sharp enough to observe?
Are your ears sharp enough to listen for flat tones?
Can you handle the risk with a good Sharpe Ratio?
Is your mind as sharp as a knife?
This is the 2nd Sharp Mathematics Contest.
The previous installation of the contest was actually pretty tough, involving some really advanced undergraduate / masters level mathematics, but the two brave contestants didn't know it, while the rest of the readers shied away from participating. With only two participants, the 3rd prize was left unclaimed. "Discretion is the better part of valour", they say?
OK, this time 'round, I am going to make it easier. I want to give away all the prizes! You just need to read and understand my post on visualising the division of fractions. Keep a sharp lookout for my posts for the next few days, as I might just drop some hints.
Prizes
The prizes, from my own Steem wallet, are:-
1st Prize: 5 SBD
2nd Prize: 3 SBD
3rd Prize: 2 SBD
If I get sponsors, then the prizes may be increased. If you know a rich uncle / daddy, or maybe some whale Steemit users who want to help out, please reply to this post, or contact moi at mathducator@hotmail.com.
So now ... are you game enough?
Are you ready for the challenge?
Here goes ...
The Challenge
Criteria
I will be judging the entries for the competition based on the following criteria:-
(1) correctness of the answer
(2) explanation of the answer, especially the concepts
These are the main criteria. If necessary, as tie-breaker, I'll use the "quality of the graphics" as an additional criterion.
How to Join the Competition
To participate in this competiton, you must do all of the following:-
(1) upvote this post
(2) resteem this post
(3) follow me @tradersharpe
(4) write your own post on Steemit
(5) reply below to this post with a link to your post
For your diagrams, you may just draw on a piece of paper, and take a photo with your mobile phone. I recommend using CamScanner (or other app) that can clean up and make perspective corrections, so that it looks very nice and rectangular. Alternatively, you may use some drawing software to do the diagrams. There are plenty of these around.
Deadline
Please submit your entry to this contest at or before 23:59 Singapore time, Sunday, 15th October 2017.
All the best!
