    Finding area of curve? (solved)

    Use limit process find area of the region between graph of the function and the x axis over the indicated interval.

    I have

    y=-2x+3 from from 0 to 1

    I have delta x= 1/n xi= 1i/n


    -2(1i/n)+3 times (1/n)

    I then have

    (-6i)/(n^2) times n(n+1)/(2)

    Did I do this correctly?

    I think I understand I have to use ((n+1)(2n+1))/((6)) as the Riemmann sum.
