    • Format Cells Number Number Custom +0.0000;-0.0000;=0.0000, Font Size 9 to 12.
    • Do Format Cells Alignment Text Alignment Horizontal Center.

  4. 4

    Input column championship labels, defined variable names and variable values in Row 1, and columns E and F:

    • Enter the label Cos into cell A1;
    • Enter the characterization Sin into prison cell B1;
    • Enter the label Radius x into cell C1;
    • Enter the characterization Radius y into prison cell D1;
    • Enter the defined variable name ShrinkExpand into prison cell E1 and adjust column size to fit;
    • Enter the divers variable proper noun X Kickoff into prison cell E2;
    • Enter the defined variable proper name Y Kickoff into cell E3;
    • Select range E1:F3 and do Insert Names Create in Right Column;

  5. five

    Enter the formulas for the "3 o'clock" Radius line to appear in the Nautical chart:

    • Enter to cell C2 the formula, without quotes, "=X_Offset"
    • Enter to prison cell D2 the formula, without quotes, "=Y_Offset"
    • Enter to cell C3 the formula, without quotes, "=C2+ShrinkExpand"
    • Enter to cell D3 the formula, without quotes, "=D2"

  6. half dozen

    Enter the Cosine (x) and Sine (y) formulas and fill down:

    • Enter to prison cell A2 the formula, due west/o quotes, "=X_Offset+COS((ROW()-two)*PI()/180)*ShrinkExpand"
    • Enter to cell B2 the formula, w.o quotes, "=Y_Offset+SIN((ROW()-ii)*PI()/180)*ShrinkExpand"
    • Edit Go To cell range A2:B362

Click on the line created and edit the Series Formula in the formula bar until information technology exactly reads as follows (but w/o quotes):
    • "=Series("Radius",'Circle Data and Chart'!$C$2:$C$three,'Circumvolve Data and Nautical chart'!$D$ii:$D$3,2)"
    • Click on the Circle. Its Series Formula should exactly read as follows -- you'll probably have to edit in "Circumference":
    • "=Series("Circumference",'Circle Data and Nautical chart'!$A$two:$A$362,'Circumvolve Data and Chart'!$B$ii:$B$362,1)"

    SIN and COS are in Excel 2007, you must write =SIN(x) or =COS(x) and for π you lot must write PI(). Excel is automatically in radians. You can detect more than information on Microsoft's official website.
