What is Caluculus

    Can anyone post an introduction to calculus?

    Your asking a bit much there my friend, entire textbooks are devoted to introducing calculus (my intro calc text is about 1500 pages). However, I am part the way through writing a brief introduction to differentiation is this thread. At the moment it only covers very basic undergrad math, but I am considering extending it when I have a little more free time. However, if you were to spend a few minutes with google I'm sure you could turn up some reasonable calc resources. If you are intending to learn calc on your own or are looking for a reference for college then I would highly recommend getting yourself a hard copy of a good textbook.

    Edit: Courtrigrad has posted a good collection of links here

    In brief here is how I would summerize calculus:

    Discussing Properties of Continuous functions in the field of All real numbers (such as limit and continuity).

    Tangent Lines and what they mean.

    A new way of adding stuff.

    There's differential calculus which addresses the tangent line problem: rates of change, instantaneousness, the derivative, etc.

    ...and integral calculus which addresses the area problem: antiderivatives, area under curves, revolution of solids about axes, etc.

    These two fields of calculus are linked by the Fundamental Theorem of Calculus.

    Calculus is the study of the instantaneous infinitesimal differentials (or tiny bits of change). In differential Calculus it focuses of the rate of change of say, y compared to x. In Integral Calculus, it focuses of the changes in area under the curve, or any line.

    I agree with most of what has been said above, although for students just starting with calculus there are a lot of good resources on the Internet.

    Calculus Resources

    Calculus 3A Multimedia Files
    PowerPoint Lectures
    for AB and BC Calculus

    Calculus for Beginners
    Calculus - by Benjamin Crowell
    Calculus Unlimited
    Calculus (Math 1314) Video Lectures
    Video Calculus

    I especially like the last two, as they present calculus in a straight-forward way with lots of examples and such.

    Thanks for the links. I was just asking what calculus is, why is it used, what special about calculus, because i study in tenth standard

    Pretty hard to give a definition to calculus because it can be applied in so many different ways and thus will be defined differently by different people. I would say that it is the application of the idea of limits to the tangent problem and the Riemann sum problem (area under curve) like most people here have said. The best way to find out is to pick up a calculus book at your library, you could probably glance over the intro pages and get some sort of idea as to what calculus is.
