I have a set of data points, and I need to find the area under the curve they form. I am trying to use Maple for this, by using the PolynomialInterpolation() to fit a curve to my list of points. I then would just integrate this function over the appropriate interval.
The problem is it that although the function it spits out gives me accurate range when I type in values manually, when I try to integrate it over the correct interval it spits out a huge number which is vastly larger than the area under the curve could be.
So now I don't know how to do this... is there another way to get the area?
