`\qbezier`

Synopsis:

\qbezier(x1,y1)(x2,y2)(x3,y3) \qbezier[num](x1,y1)(x2,y2)(x3,y3)

Draw a quadratic Bezier curve whose control points are given by the
three required arguments `(`

,
`x1`,`y1`)`(`

, and `x2`,`y2`)`(`

. That is,
the curve runs from `x3`,`y3`)`(x1,y1)` to `(x3,y3)`, is quadratic, and is
such that the tangent line at `(x1,y1)` passes through
`(x2,y2)`, as does the tangent line at `(x3,y3)`.

This draws a curve from the coordinate (1,1) to (1,0).

\qbezier(1,1)(1.25,0.75)(1,0)

The curve’s tangent line at (1,1) contains (1.25,0.75), as does the curve’s tangent line at (1,0).

The optional argument `num` gives the number of calculated
intermediate points. The default is to draw a smooth curve whose
maximum number of points is `\qbeziermax`

(change this value with
`\renewcommand`

).
