Bézier curves are used in PhotoShop, animation, auto manufacturing, film special effects, higher math curve analysis and for many other functions. In this article, learn to use Bézier curves and the formulas they're based on to create Excel charts of curves, which are exacting. Bézier curves can also handle rational curves, like circles, with a bit of math tweaking -- but that's reserved for a subsequent article, if sufficient interest is generated. You'll be learning three types of curves in this article: the straight line's interpolation, the quadratic curve and the cubic curve. Bézier curves are not limited to 2 dimensions but can visualize more, many more in fact, which is one reason math pros find them very, very exciting! The math presented here is not terribly difficult and while some derivatives will be shown since Bézier curves are used to calculate the rate at which an object moves along a curve, they will not be much elaborated upon for now.

### Open a new Excel workbook and prepare 2 worksheets:

- Either click on the green “X” icon, or double-click on Excel in the Microsoft Office folder in your Applications folder by opening a Finder window, in order to start Excel;
- Using the File menu or the icon, Open a new workbook;
- Save the workbook as “Bezier Curves” into a logical folder, such as “wikiHow Articles” or “MS XL Imagery”;
- Create via the + button at the bottom or access the second worksheet tab and double-click edit-name it “Saves” — this will be used to Paste Values and Charts to which you wish to keep and remember, while still having the top worksheet tab for doing the main work on — if you were to copy and paste, the formula results would change with varying inputs on the top worksheet from the Defined Named Variables, which are global;
- Double-click on the first leftmost worksheet tab and edit-name it “3 Curves” (w/o quotes).

## Do Quadratic Bezier Curve

### Familiarize yourself with the basic facts of the Quadratic Bézier Curve:

- A quadratic Bézier curve is the path traced by the function b(t), given points P0, P1 and P2.
- B(t) = (1-t)*[(1-t)P0+t*P1] + t*[(1-t)*P1 + P2], where t is an element in the range [0,1], inclusive, which can be interpreted as the linear interpolant of corresponding points in the linear Bézier curves from P0 to P1 and from P1 to P2 respectively.
- Rearranging the preceding equation algebraically gives:
- B(t) = (1-t)^2*P0 + 2*(1-t)*t*P1 + t^2 * P2, where t is an element in the range [0, 1], inclusive.
- The derivative of the Bézier curve with respect to t is
- B´(t) = 2*(1-t)*(P1 – P0) + 2*t*(P2 – P1), from which it can be concluded that the tangents to the curve at P0 and P2 intersect at P1.
- As t increases from 0 to 1, the curve departs from P0 in the direction of P1, then bends to arrive at P2 from the direction of P1.
- The second derivative of the Bézier curve with respect to t is:
- B´´(t) = 2*(P2 – 2*P1 + P0].
- A quadratic Bézier curve is also a parabolic segment. As a parabola is a conic sector, some sources refer to quadratic Béziers as “conic arcs”.
- Enter the sub headers and formulas which create the chart:Enter t to cell A34; enter X P0 to cell B34; enter Y P0 to cell C34; enter X P1 to cell D34; enter Y P1 to cell E39; enter X P2 to cell F34; enter Y P2 to cell G34; enter ((1-t)^2+(1-t)t*P1+t^2* P2)*Interpolater to cell K39 and also to cell L39;Enter .2 to cell A35; enter 1 to cell B35; enter 3 to cell C35; enter 2 to cell D35; enter 1.5 to cell E35; enter, w/o quotes, “=A35” to cell A40; copy cell A40 and paste it to cell range B40:G40; enter to cell K40, w/o quotes, the formula “=((1-t)^2+(1-t)*t*Psub1_X+t^2*Psub2_X)*Interpolater” and Format Cells Font Red [Result=1.2280]; enter to cell L40, w/o quotes, the formula “=((1-t)^2+(1-t)*t*Psub1_Y+t^2*Psub2_Y)*Interpolater” and Format Cells Font Red [Result=1.0400](given the Interpolater = 1);

- For Series#2, title it P0, B(t)i, P2; set X-series to $N$39:$N$41 and set Y-series to $039:$O$41;
- These steps may not turn out right: Check by clicking on the first data series that its formula in the formula bar reads,
- “=SERIES(“P0, P1i, P2″, Sheet1!$N$33:$N$35,Sheet1!$O$33:$O$35,1)”
- and that the formula in the formula bar for the second data series reads,
- “=SERIES(“P0, B(t)i, P2″,Sheet1!$N$39:$N$41,Sheet1!$O$39:$O$41,2)”, w/o quotes.
- Format the Axes, Vertical Gridlines and Axes Titles as you did for the Linear Chart above;
- Do Chart Layout, Chart Title, Format Title, Text Box and check Resize shape to fit text;
- Edit-click in the new Text-Box title box and title the chart Bézier Quadratic Curve (return) P0, P1i, P2 and P0, B(t)i, P2; OK.
- Drag the chart so that its upper left corner is in cell M19 and resize it so its lower right corner is in cell Q31.
- Except for some Data Marker Styles and Fill and perhaps a few other details, your chart should resemble this one: WH.shared.addScrollLoadItem(‘ad7468f5e6775a214d6fd20b74b75760’)

## Do Cubic Bezier Curve

### Familiarize yourself with the basic facts of the Cubic Bézier Curve:

- Four points P0, P1, P2 and P3 in the plane or in a higher dimensional space define a cubic Bézier curve.
- The curve starts at P0 going toward P1 and arrives at P3 coming from the direction of P2. Usually, it will not pass through P1 or P2; these points being there only to provide directional information.
- The distance between P0 and P1 determines “how long” the curve moves into direction P2 before turning towards P3.
- Writing BPiPjPk(t) for the quadratic Bézier curve defined by points Pi, Pj and Pk, the cubic Bézier curve can be defined as a linear combination of two quadratic Bézier curves.
- B(t) = (1-t)*BP0,P1,P2(t) + t*BP1,P2,P3(t), with t as an element in the range [0, 1], inclusive.
- For some choices of P1 and P2, the curve may intersect itself, or contain a cusp.
- Any series of 4 distinct points can be converted to a cubic Bézier curve that goes through all 4 points in order.
- Given the starting and ending point of some cubic Bézier curve, and the points along the curve corresponding to t = 1/3 and t = 2/3, the control points for the original Bézier curve can be recovered.
- The derivative of the cubic Bézier curve with respect to t is
- B´(t) = 3*(1-t)^2 * [P1 – P0] + 6*(1-t)*t*(P2 – P1) + 3*t^2 *(P3 – P2).
- The second derivative of the Bézier curve with respect to t is:

- Enter the sub headers and formulas that create the chart:Enter t to cell A71; enter X P0 to cell B71; enter Y P0 to cell C71; enter X P1 to cell D71; enter Y P1 to cell E71; enter X P2 to cell F71; enter Y P2 to cell G71;Enter ((1-t)^3*P0+3*(1-t)^2*t*P1+3*(1-t)*t^2*P2+t^3* P3)*Interpolater to cells K71, L71, K76, L76, K82 and L82;Enter .5 to cell A72; enter -3 to cell B72; enter -4 to cell C72; enter -.5 to cell D72; enter 1 to cell E72; enter -1 to cell F72; enter 3 to cell G72; enter 4 to cell H72; enter 1 to cell I72;Enter, w/o quotes, “=1/3” to cell A77; enter, w/o quotes, “=B72” to cell B77 and copy cell B77 and paste it to cell range C77:I77;Enter, w/o quotes, “=2/3” to cell A83; enter, w/o quotes, “=B77” to cell B83 and copy cell B83 and paste it to cell range C83:I83;Enter in cell A85, the text w/o quotes, “For further information, see:” and enter in cell A86 http://en.wikipedia.org/wiki/B%C3%A9zier_curve which then step into in the formula bar and edit it at the middle/end of it, adding nothing, press return, and it should become a live link;Enter to cell K72, w/o quotes, the formula “=((1-t)^3*Psub0_X+3*(1-t)^2*t*Psub1_X+3*(1-t)*t^2*Psub2_X+t^3*Psub3_X)*Interpolater” and Format Cells Font Red [Result=-0.8125]; copy this same formula and paste it to cells K77 and K83 [where the results are -1.2963 and -0.3704, respectively];Enter to cell L72, w/o quotes, the formula “=((1-t)^3*Psub0_Y+3*(1-t)^2*t*Psub1_Y+3*(1-t)*t^2*Psub2_Y+t^3*Psub3_Y)*Interpolater” and Format Cells Font Red [Result=+1.1250]; copy this same formula and paste it to cells L77 and L83 [where the results are -0.0370 and +1.7037, respectively];
