Riemann Stieltjes Integral help!

  1. Feb 24, 2010 #1
    Code (Text):

    Let f =

    x, for 0<=x<=1
    1, for 1<x

    alpha =

    x^2, for 0<=x<=1
    1, for 1<x
    Find Integral (f) d(alpha) -- from 0 to 23

    pls help!

    Use the definition of the R-S integral. The answer should pop right out unless I'm missing something. Where does the problem lose you?

    This case easily translates into an ordinary Riemann integral.
    dα = 2xdx, 0≤x≤1
    dα = 0, x>1
