How Do I Integrate?
I have a spreadsheet of about 100 data points of independent variables and
matching values for dependent variables. I want to integrate the resulting curve to find the area underneath. How do I do this? |
How Do I Integrate?
Myles,
To calculate the area under a curve, you can use =SUMPRODUCT(A3:A100-A2:A99,(B3:B100+B2:B99)/2) Where your x values are in A2:A100, and your Y values are in B2:B100. This is an approximate method for finding the area under the curve, summing the area of the trapezoids defined by pairs of points (and the points along the x axis).
