Area under a CurveThe area between the graph of y = f(x) and the x-axis is given by the definite integral below. This formula gives a positive result for a graph above the x-axis, and a negative result for a graph below the x-axis....
Where did this formula come from? Area Under a Curve from First Principles In the diagram above, a "typical rectangle" is shown with widthΔx\displaystyle\Delta{x}Δxand heighty\displaystyle{y}y. Its area isyΔx\displaystyle{y}\Delta{x}yΔx. ...
Put in the following formula, which is a calculation to find the area under the line. As shown below, each individual formula shows the area under the graph between the data points. In this case, we type((Y Value 2) + (Y Value 1)) / 2 * (X Value 2 – X Value 1) 2. Drag ...
I can use a simple SUM formula to do this. So this is how I can calculate the total area under the curve for a simple line chart. Note that the result of this method would be very close to the actual area under curve value, it could be slightly off. This is because the area betw...
This will open a chart like the one below. Calculate the area of the trapezoid which is between X = 1 & X = 3 under the curve by entering the following formula in cell D5: =((C5+C6)/2)*(B6-B5) Press Enter. Use the Fill Handle tool till the second last cell to get the area...

Area between two curves is given by difference of area under individual curves. Formula Used: {eq}\displaystyle \int x^n dx=\frac{x^{n+1}}{n+1}+c. {/eq} Answer and Explanation:1 a. Given curves {eq}\displaystyle y = x^2 {/eq} and {eq}\displaystyle y=x...
How to Find the Area Under Curve in Microsoft Excel: Steps Example question: Find the area under curve in Excel for the graph below, from x = 1 to x = 6. Step 1: Choose a few data points on the x-axis under the curve (use a formula, if you have one) and list these values ...
To calculate the area under a plot, you'll have to separately calculate the area between every two values and then sum them to get the total area. This might sound a bit arduous, but don't be daunted. It's easier than it looks. ...
