With the Olympics being held in London in 2012 it seemed appropriate to make some TI-Nspire documents based around sport. Since I have some experience of competitive cycling I choose this as a topic. This file was produced after I asked myself ?where's the maths in that??
The TI-Nspire document is split into 4 different activities.
Activity 1 ? Frame Geometry
Are all cycle frames the same? Use TI-Nspire to make measurements of images of cycles gathered from the web and to compare angles and ratios of lengths.
Activity 2 ? Track Statistics
Are all cycle tracks the same? Compare the features of 25 tracks around the world using data provided. Then add more data to reach more reliable conclusions.
Activity 3 ? Track Dimensions
The lengths of the straights and the radii of the ends of cycle tracks vary. Build a model track so that it has a particular overall length.
Activity 4 ? A Fermi Problem on gear ratios
How many times do a bike?s pedals rotate during one lap of a cycle track?
