You'll learn to make the "Necklace" pattern and image below, and the dozens of variations the file permits therefrom.

### Part 1 The Tutorial

- 1
**Unlike the preceding workbooks, this one does not build on previous efforts and does not require knowledge of them to be implemented.**However, a basic understanding of design principles, such as what happens to a curve when one adds to it versus when one multiplies to it, would be helpful. Here, a basic adjustment is added to the Garthwaite Curve. That adjustment happens to be {0,0} but the user is encouraged to substitute their own values and observe the effects of so doing. - 2
**Set Preferences.**Open Preferences in the Excel menu. Recommended Settings: Set General to R1C1 Off and Show the 10 Most Recent Documents; Edit - set all the Top options to checked except Automatically Convert Date System. Display number of decimal places = blank (for integers preferred), Preserve display of dates and set 30 for 21st century cutoff; View - show Formula Bar and Status Bar, hover for comments and all of Objects, Show grid lines and all boxes below that auto or checked; Chart - show chart names and data markers on hover. Leave rest unchecked for now; Calculation -- Automatically and calculate before save, max change .000,000,000,000,01 w/o commas if you do goal-seeking a lot and save external link values and use 1904 system; Error checking - check all; Save - save preview picture with new files and Save Autorecover after 5 minutes; Ribbon -- all checked except Hide group titles and Developer. - 3
**Create the Defined Variables upper section of the Data worksheet.**- Enter AROWS into cell A1 and 1439 into cell A2. Insert Name Define Name AROWS to cell $A$2. "AROWS" stands for Adjusted Rows.
- Enter FACTORY into cell C1 and -.25 into cell C2. Insert Name Define Name FACTORY to cell $C$2.
- Enter GM into cell D1 and w/o spaces 0.618 033 988 749 895 into cell D2. Insert Name Define Name GM to cell $D$2.
- Enter Adj1 into cell G1 and 0 into cell G2.
- Enter Adj2 into cell H1 and 0 into cell H2.
- Command-Select cells A2, C2, D2, G2 and H2 and Format Cells Border Black Outline. Select cell range A1:H2 and align horizontal center.

**Create the Column Headings section of the Data worksheet.**- Enter Base t into cell A3.
- Enter c into cell B3.
- Enter cos into cell C3.
- Enter sin into cell D3.
- Enter x into cell E3.
- Enter y into cell F3.
- Enter AdjX into cell G3.
- Enter AdjY into cell H3.
- Select A3:H3 and align center and Font underline single underline.

- 5
**Enter the Column Formulas.**- Enter "=ROUND((308100*PI())+(190),0)" w/o quotes into cell A4. Format Cell Number Number Custom "tip" 0 including quotes. Insert Name Define Name tip to cell $A$4.
- Edit Go To cell range A5:A1444 and with A5 active, enter w/o quotes the formula "=((A4+(-tip*2)/(AROWS)))" into A5 and Edit Fill Down.
- Select cell B4 and enter -25822 into it. Edit Go To cell range B5:B1444 and with B5 active, enter "=B4" w/o quotes into it and then Edit Fill Down.
- Edit Go To cell range C4:C1444 and with C4 active, enter w/o quotes the formula into it, "=COS((ROW()-4)*PI()/180*FACTORY)". Factory Note: .25*1440 = 360, one full circle/cycle.
- Edit Go To cell range D4:D1444 and with D4 active, enter w/o quotes the formula into it, "=SIN(ROW()-4)*PI()/180*FACTORY)".
- Edit Go To cell range E4:E1444 and with E4 active, enter w/o quotes the formula into it, "=((SIN(A4/(B4*2))*GM*COS(A4)*GM*(COS(A4/(B4*2)))*GM)+C4)+SIN((SIN(A4/(B4*2))*GM*COS(A4)*GM*(COS(A4/(B4*2)))*GM)+C4)+AdjX" and Edit Fill Down. This is a double whammy.
- Edit Go To cell range F4:F1444 and with F4 active, enter w/o quotes the formula into it, "=((SIN(A4/(B4*2))*GM*SIN(A4)*GM*(COS(A4/(B4*2)))*GM)+D4)+COS((SIN(A4/(B4*2))*GM*SIN(A4)*GM*(COS(A4/(B4*2)))*GM)+D4)+AdjY" and Edit Fill Down,
- Select cell G4 and enter 0 and select cell H4 and enter 0. Edit Go To cell range G4:G1444 and Edit Fill Down and Insert Name Define Name AdjX to cell range $G$4:$G$1444. Edit Go To cell range H4:H1444 and Edit Fill Down and Insert Name Define Name AdjY to cell range $H$4:$H$1444.

### Part 2 Explanatory Charts, Diagrams, Photos

- (dependent upon the tutorial data above)

**Create the Chart.**- Edit Go To cell range E4:F1444 and, using either the Chart Wizard or the Ribbon, select Chart, All/Other, Scatter - Smooth Line Scatter. If not using Chart Wizard, a small chart should appear atop the data. Copy or Cut and Paste the Chart to the Chart worksheet you create anew now, into cell A1, and expand the chart by hovering over the lower right corner until the cursor becomes the double-headed arrow allowing one to pull down and to the right the chart, expanding it. Using Chart Layout, Select Data Series 1 and Format Selection Line Weight 1. Then select the Plot Area and format Fill grey. Then format Chart Area sky blue fill. Insert Picture WordArt whatever text you feel is appropriate, and format it by clicking on the Home Ribbon tab and using the edit tools.
- Hold down the shift key and copy picture to the Saves worksheet to be created anew, along with the formulas and pasted values from the top rows of the Data worksheet.
- It would be a good idea to Insert New Comment on the original values and formulas of the Data worksheet so that renormalization is a few steps away. Done.

## Warnings

- ERRORS: If there are errors or error values, either the sheet in incomplete and needs further input or Lookup Tables for critical variables or perhaps there's a mistake somewhere along the line. If the instructions have been completed and there are still errors, select the cell that has the error value that is furthest left and topmost first. Look for a typo in a formula or unmatched parentheses. Possibly, a Defined Name is wrong -- they need to be input into the formulas exactly as they were defined. Do Insert Name Define to check. If there is a #DIV/0! error, the example does not, so look for a variable that somehow did not get filled in with a value perhaps. At any rate, what to do is select the cell with the error, and after checking all those typical errors, do Tools Auditing Trace Precedents and/or Trace Error. If fixing all the topmost leftmost errors does not fix the rest of your errors on the worksheet, one may need to do it the hard way, from the bottom right upwards then leftwards; that is the slow but sure way to fix all errors.
- Errors in the chart data will most likely plot as zeroes. This may be acceptable or desirable even. However, if too many lines (or curves) are returning to 0, it may indicate a logical flaw in the data -- or too many tiny values and then perhaps rescaling the chart is needed by inspecting the horizontal and vertical axes and changing them to zero in on the problem. Hover over or click on a data marker on the series plot and then do a search in the proper column by value for that value, and identify its precedents.
