Integration and area under curve

  1. Jan 11, 2010 #1
    I have seen a thread with a similair title but passed up on what i want to know.

    I just want somebody to explain to me why definite integration equals the area under between the function and the x axis

    Ive just been through indefinite integration, then using the summation formulas in my AP calculus class, and i understand the concept of going from acceleration to velocity to position, but i dont understand how that can equal the area under a curve.

    this whole question might be pointless because we havent learned how to evaluate definite integrals yet and maybe my answer lies in that.

    Any 2 cents worth is appreciated!!!
