How to use The text input fields can accept real numbers in decimal notation. The buttons under the graph allow various manipulations of the graph coordinates.
Shown here by the four points: (x1,y1) -- (x2,y2) -- (x3,y3) -- (x4,y4)
Other Notes
The graph goes through the endpoints (x1,y1) and (x4,y4), with (x2,y2) and (x3,y3) as "control points." The endpoints and control points for the Bezier curve are colored red in the graph, and the line segments between the endpoints and their corresponding control points (indicating tangent vectors at the endpoints) are colored green.
