    Area under the curve

    Hi,

    This is a stupid question but if i have a plot of mmolO2/(l*hours) vs hours, and i get the area under the graph what will i have?

    I am trying to get the total amount of mmolO2 i have fed for a set time but not sure how.

    Appreciate any help,

    Thanks rem

    (sorry if this is the wrong place to post)

    What, exactly, are you integrating? What is the function representing the integrand? Or, if you are supposed to be working from a picture, what is that picture?

    Thank you!

    Please provide a detailed description of the picture, or else (which is likely better) provide a scan of the graphic.

    Thank you!

    Here is a bitmap of it.

    It shows a feed of air which is (m mol O2/(litre*hour)).

    Thanks

    If you have a count of the number of liters fed in each unit of time, can't you just add these up?

    (It might help if you provided the full and exact text of the exercise.)
