Calculate Area Under Curve in Excel (2 Easy Ways)

It’s possible that in order to understand the integral, you had to first draw and color a plotted curve, and then compute the area of the shaded portion. The area under a plotted curve may be calculated in Excel using two methods described in this article.

• Using the Trapezoidal rule, determine the area under a plotted curve.
• Using a chart trendline, determine the area under a plotted curve.

The vast majority of your issues may be resolved with Microsoft Excel course, which boosts output by an astounding 80 percent.

Any formulae, charts, or other items you often use may be saved as favorites so that you can simply re-use them in the future.

There are more than 20 features to choose from: Text-to-number conversion; Remove or Edit a Section of a Text; English words can be translated from numbers and currencies.

Multi-Workbook/Multi-Sheet Merge; Data-Safe Merging of Multiple Rows/Columns/Cells; Merging of Duplicate Rows/Sums.

Multiple-sheet splits based on value are possible using the Split Tools. Many Excel, PDF, or CSV files may be generated from a single workbook, and a single column can be used to generate multiple columns in any of these formats.

Count and Sum by Background Color; Skip Hidden/Filtered Rows. Mass-Send Customized Emails to a Large Amount of People.

Create complex filter schemes and apply them to any document with the Super Filter. Select from a wide range of options including weekdays, days of the week, frequency, and more. Use bold, formulae, and comments to narrow down your search results.

All languages supported; More than 300 features; Office 2007-2019 and 365 compatibility; Your firm or group will be able to easily implement this.

Use The Trapezoidal Rule to Determine the Surface Area Under a Plotted Curve

For instance, as seen in the picture below, you’ve produced a plotted curve. The area between the curve and the x axis will be divided into numerous trapezoids, with each trapezoid’s area being calculated separately and then summed.

x=1 and x=2 are the points where the first trapezoid is located beneath the curve, as illustrated in the screenshot. The formula for calculating its area is =(C3+C4)/2* (B4-B3).

Second, drag the AutoFill handle down to compute additional trapezoids’ areas.

We now know how big each trapezoid is. To determine the entire area beneath the plotted area, enter the formula =SUM(D3:D16) in a blank cell.

Using a Trendline Chart, Estimate the Surface Area Under the Plotted Curve

The displayed curve’s equation will be derived from the chart’s trendline, and the definite integral of that equation will be used to determine the area under the shown curve.

Select the chart you want to design, then click Design (or Chart Design) > Chart Design Add Element to Chart > Trendline > Additional Trendline Options.

In the Format Trendline pane:

• One choice that best fits your curve might be found under Trendline Options.
• Select the option to show the equation on the chart.
• After that, the equation is inserted into the graph. Calculate the definite integral of the equation by pasting it into sprintzeal your spreadsheet.

F(x) = (0.0219/3)x3 + (0.7604/2)x2 + 5.1736x + c is the definite integral of my general trendline equation y = 0.0219×2 + 0.7604x + 5.1736.

x=1 and x=15 is now plugged into the definite integral, and the difference between those two values is calculated as shown in Step 4. The difference between the plotted curve’s area and the difference between the plotted curve’s area is the difference.

Enhanced Capabilities

• Shortcuts abound.
  

Many built-in and user-defined shortcuts may be used to manage tabs, hide/show the Tab Bar, navigate between tabs, and select individual tabs in Office Tab. It’s simple to create custom keyboard shortcuts.

• The Tab Bar Is Visible or Not
  

The Tab Bar may be positioned anywhere along the workspace’s top, bottom, right, or left edge. A single tab may even be used to conceal the Tab Bar. The Tab Bar may also be shown or hidden by using a custom shortcut key (the default is “Win + Q”).

• Documents that are freely available
  

“Open,” “Open in New Window,” and “Open Folder” are all available from the Context Menu. To open more than one tabbed window, just choose an existing file or folder and click the Open button.

• It’s a one-stop shop for all your settings.
  

The Office Tab Settings Center is a comprehensive tool for customizing Office Tab. Each tab may be enabled or disabled individually, shortcuts can be used (or not), the Tab Bar can be shown in top or bottom or left or right position and the Tab Style and tab colors can be customized using the Tab Center.

• Create a New File
  

Simply double-clicking the left button on the Tab Bar’s blank area, or selecting “New” as an option from the Context Menu will create a new document.

• Backup Your Files
  

In the context menu, the “Save All” and “Save All” commands may be used to save all the documents at once. An asterisk (*) in the file name indicates that the document or worksheet has been edited by Office Tab.

• Shutdown Documents
  

Context menu choices include the following: “Close, Close All,” and Close Other, giving users a choice of how to close currently open files. The opened document may be swiftly closed by pressing the middle mouse button or by double-clicking the tab’s left button.

• Tab Length may be altered.
  

You may choose between an automated, self-adaptive, or fixed length for the tabs. The file name is shown as much as possible in the automatic display. File names are automatically resized to fit the width of the tab they’re shown on. All of the tabs are the same length when using a set tab length.
