Part A 1. Copy the items in your spreadsheet from Step 1 and paste them elsewhere in the same spreadsheet page. 2. Use spreadsheet again to estimate the area that lies under the curvey = x + 1 between x = 0 and x = 10 this time letting the number of sub- intervals be n = 20. . First calculate the area using the left endpoints and then right endpoints. 3. Use spreadsheet software once more to: Estimate the area that lies under the curvey = x + 1 between 0 and 10 . Let n = 20 Calculate the area using midpoints. Insert a screen capture of your spreadsheet.
