area between two curves calculator program

I really appriciate if you can help me improve this method. But I am sure this is not the correct way, I totaly have no idea what is the result of the method I ems to be difference between Voltage points only. If the result is somehing near 0 eg 0.05 then the difference between curves is negetable. Select AREA from the menu, and watch it go.

This code somehow works, having in mind I do nothing with Current (vertical axis). Either enter the upper and lower expressions in Y1 and Y2 (and select that the exps are already in Y1 + Y2) or select that the exps are not in Y1 + Y2 and enter them as prompted (as in this example.) Then enter the lower and upper bounds for the integration. Min = Math.Min(Math.Abs(pin1), Math.Abs(pin2)) Max = Math.Max(Math.Abs(pin1), Math.Abs(pin2)) With just a few modifications, we extend the application of definite integrals from finding the area of a region. What I am doing at the moment is like this: public double CalculateArea(double pin1, double pin2)ĭouble currentArea = 0 //Current (Vertical axis) not yet!įor (int i = 0 i < pin1.GetLength(0) i++) There are 51 data points for each curve (they always have same amount of data poitns).

I want to calculate the area between this two curves (BLUE curve is first diode and RED is the second one). I am working on a program that compares two curve (resulted from diode output so its Voltage/Current curve).
