Simple Tips for Better Maths Results!
I came across this interesting image and would like to share with all of you.
This is to do with finding volume of a figure (example cylinder).
Volume of cylinder = PI * r^2 * h
r: radius, h: height
In general, to find the volume of a cylinder (or prism) = cross-sectional area * height.
Together with Sean Chua of SimpleChemConcepts.com we took a 9 days educational trip to Northern Vietnam, Hanoi.
It was an eye opener for us to be in the countryside, seeing terrace cultivation, outlines of mountains and mountains, experiencing the beauty of UNESCO world heritage site - Ha Long Bay. I did a video as well.

It's a drastic change compared to city life. People's lifestyle in the Sapa villages are less developed, slower. Children there are seen to be playing with traditional games like marbles. They were left to play on their own by the streams, on the soil.
However, the first thing I was overwhelmed is the traffic in Hanoi city: endless honking of the motorcycles. We hardly use traffic lights to cross the busy roads, we simply walk across quickly. It's amazing how the locals travel around the busy roads. Traffic is a big part of our experience in Hanoi!
A common sight in Hanoi is that you will find locals, young and old sitting by the road side for a cup of tea, eating a bowl of noddles (known as 'Pho') or just catching up with one another. We have a few experiences too. You got to be willing to exchange air con with road side air and don't expect cleanliness that of Singapore!
From Wikipedia:
The Tower of Hanoi or Towers of Hanoi (also known as The Towers of Brahma) is a mathematical game or puzzle. It consists of three rods, and a number of disks of different sizes which can slide onto any rod. The puzzle starts with the disks neatly stacked in order of size on one rod, the smallest at the top, thus making a conical shape.
The objective of the puzzle is to move the entire stack to another rod, obeying the following rules:
This might be a simple game but it is a great tool to train your logic thinking.

You can try it with different number of disks. They even added the challenge of completing the game in the minimum moves. Solution is also provided should you face challenges in completing!
Have Fun!

I will be back in the next post to discuss on different approaches to a Additional Mathematics on Identity which falls in the topic of Factor Remainder Theorem. Look out for the next post!

I made a trip to Genting Highland last week as a short getaway from the hot weather in Singapore. Here are some of the highlights. Personally I think that the power tower is well taken, don't you think so?
I guess many of you have also travelled overseas during this holiday to recharge and be ready for year 2009! Another exciting year ahead!
Share with me in the comments section where you travelled to and perhaps a photo or so to sum up the highlight of your trip would be awesome!
This is the result for the poll conducted last month.
