Lower sum/ upper sum

  1. Jul 20, 2012 #1
    1. The problem statement, all variables and given/known data

    Give the upper sum for f(x)=4-x2 on the interval [-1,1] with respect to the partition P{ -1, -0.5, 0.5, 1]

    Give the lower sum for f(x)=4-x2 on the interval [-1,1] with respect to the partition P{ -1, -0.5, 0.5, 1]


    2. Relevant equations



    3. The attempt at a solution

    How do I do this again? Lower sum should be the area under the curve. You'd just integrate then on the interval given (-1,1) ? Also don't know anymore how to do upper sum.

    No, it would not.
    No.

    Apparently not. Start by writing the definitions. They will be in your text.
