Maths in uses?

In my country, Cambodia, the education is not so practical. In my class in high school, most math lessons are tough as theories alone, no practice or experiment.

Mostly, i can find the solution of a math problem, but i always questioned that why find the solution? what is it used for? What is the main purpose of complex numbers, derivation, integration, etc...? (i can't find the exact name, since my teachers use french terms in math)

Please... Any body recommend any good books or websites that explain about the uses of math. :)

Complex numbers have probably their most useful application in engineering because without them we can't model damped or forced oscillations (amongst plenty of other things(. Differentiation (the process of finding derivatives) is used by statisticians to analyse things like population growth and their findings on that kind of thing are often important to the running of a country. Integration's main use is solving the differential equations that describe the material world (and also for slightly less significant but equally useful purposes such as finding centres of mass of complicated bodies).

I can't suggest a book because I don't know of one, all of that came straight from my head.

complex numbers describe rotations, derivatives rates and integration volumes, math is used anywhere and everywhere, to point to anything specific would be discriminating the others..

It's also used when making computer games - and programming in general... For example the calculation of a ballistik missile for a tank game, though you wouldn't calculate it as if it was the real world, you'd still need math to figure out how to make it fly =)

Cheers!

The amount of calculations performed by your graphics card while displaying this screen may surprise you.

What about the amount of calculations the processor does just by running windows?

CHeers

The mean number of CPU operations between fatal Windows crashes = 17.
