We can create poly-Bézier curves by connecting several individual curves. Test the connection after each redefinition by dragging all control points. I. Connect only the endpoint D of the first curve to the first point E of the second curve: [list=1] [*]In the input box enter: [math]E=D[/math] [*]Test the connection. [/list] II. Redefine the second control point F of the second curve so that the two Bezier curves have the same tangent line at their common point: [list=1] [*]Enter [math]l=line[C, D][/math] in the input box. [*]Redefine F by entering [math]F=point[l][/math] [*]Test the connection. [/list] III. Make the two distances from the common point to the respective control point equal: [list=1] [*]Enter in the input bar: [math]C'=Reflect[C, D][/math] [*]Redefine F by entering [math]F=C'[/math] [*]Test the connection. [/list]
