Your odometer measures your total distance travelled. If your odometer's broken you can still estimate how far you've gone by taking an odometer reading every ten seconds, using distance = rate x time to estimate how far you went in that ten seconds, and then adding up all those D = RT calculations. You can get a better estimate if you read the odometer every 5 seconds ... and an even better estimate if you read the odometer every 1 second. Continuing this way, you can get the total distance travelled by integrating the derivative of your position function. That's the fundamental theorem of calculus.

The derivative of sin(x) is cos(x) and the derivative of cos(x) is -sin(x), is that what you mean?

The derivative is the instantaneous rate of change of some quantity. The integral is the accumulated change over time. There are applications literally everywhere, from physics to economics and biology.

Are you studying calculus? They should have some applications in your book.

It's difficult to advise you on programming something you don't yet understand, especially when you haven't said what you want the program to accomplish. Thanks from integration
