Hey All, (apologies, for not using the correct format, but this is a slightly different style of query.) First post on this forum, so.. Hey. Anyway, to get to the point.. I live in Ireland, and i'm doing a program called the IB. It more or less covers the last two years of American High School, i think.. One of the requirements is that we write an extended (4000 word) essay on an academic topic. I've been considering writing it on Maths, but not quite sure where to start. It has to be a fairly specific title, and as I'm hoping to study engineering in college, i was thinking of a title along the lines of "Applications of Differential Calculus in Engineering". I was wondering whether you guys would know a good place to start on this topic. Books to read, weblinks, even just a basic overview of topics that would rely strongly on differential calculus. We cover diff. fairly well, although it'll probably be next year before we get to the "Applications of Diff. Calc." section. If you have any suggestions on the best place to start looking, or even a better, more specific title, then it'd be welcome.. Apologies if this isn't the correct topic for this board, or even the forum in general. _Kar.
