The main point of the two reading assignments for tomorrow (9/2/2008) is to understand how exponential functions work and learn about possible applications in natural and social sciences.
I found some aspects of the exponential growth and decay in section 1.7 to be somewhat challenging, yet very interesting. Particularly I thought that the present and future value of money and the compounding effect was at first a little hard to grasp. One thing that I still do not quite understand was why the number e (2.71828..) was used when interest is compounded continuously and not when compounded annually, what is special about e?
Most interesting was the relevance to everyday life this math has! I am excited to learn how to manage my future earnings with this type of math knowledgeJ It was also great to refresh how to calculate population growth rates and the half life of compounds which I can use in other social and natural science classes.
