Hi,

I have just entered grade 11 in the IB curriculum. This is the 2nd week of school and the school has assigned a math IA which does not count towards the final IB score however it represents 20% of every math's grade on my report card. The math should not be lower than grade 10 level or too complex that I will not be able to understand it. I prefer to choose something from an automotive area. Any ideas? These are the broad areas we can choose from:

• Navigation – right angle and non-right angle trigonometry
• Building a snow terrain park – eg amount of snow required, etc.
• Statistics (bivariate analysis) – eg correlation between a country’s healthcare expenditure and life expectancy, etc.
• Voronoi diagrams – school catchment areas, spread of the plague, etc.
• Finance – compound interest, repayments, the rule of 72, etc.
• Paper sizes
• Modelling with exponential growth or decay – eg. population growth, bacteria growth, endangered species decay, etc.
