例  (2)

3つの点を通る円弧：

Wolfram Language code: pts = {{Sqrt[2], 0}, {1, 1}, {0, Sqrt[2]}};
Wolfram Language code: CircularArcThrough[pts]

円弧を表示する：

Wolfram Language code: Graphics[{%, Red, Point[pts]}]

点の集合を通る円弧のArcLength：

Wolfram Language code: ArcLength[CircularArcThrough[{{(1/2), (Sqrt[3]/2)}, {-(1/2), (Sqrt[3]/2)}, {-1, 0}}]]

スコープ  (3)

CircularArcThroughは座標に使うことができる：

Wolfram Language code: CircularArcThrough[{{1, 0}, {1, 1 / Sqrt[2]}, {0, 1}}]

複数の点：

Wolfram Language code: CircularArcThrough[Point[{{0, 0}, {1, 0}, {0, 1}}]]

円弧の中心について制約条件を指定する：

Wolfram Language code: CircularArcThrough[{{0, 0}, {1, 0}, {0, 1}}, {1 / 2, 1 / 2}]

半径についての制約条件：

Wolfram Language code: CircularArcThrough[{{0, 0}, {1, 0}, {0, 1}}, {1 / 2, 1 / 2}, 1]

CircularArcThroughは2Dの点に使うことができる：

Wolfram Language code: CircularArcThrough[{{0, 0}, {1, 0}, {0, 1}}]

アプリケーション  (3)

基本的なアプリケーション  (3)

3点を通る円弧を可視化する：

Wolfram Language code: Graphics[{CircularArcThrough[pts], Red, Point[pts]}]

3点を通る円弧の陰的表現を求める：

Wolfram Language code: RegionConvert[CircularArcThrough[{{Sqrt[2], 0}, {1, 1}, {0, Sqrt[2]}}], "Implicit"]

パラメトリック表現：

Wolfram Language code: RegionConvert[CircularArcThrough[{{Sqrt[2], 0}, {1, 1}, {0, Sqrt[2]}}], "Parametric"]

三角形の外接円を求める：

Wolfram Language code: pts = {{Sqrt[2], 0}, {1, 1}, {0, Sqrt[2]}};
Wolfram Language code: CircularArcThrough[pts]
Wolfram Language code: Graphics[{%, Red, Triangle[pts]}]

特性と関係  (5)

CircularArcThroughはCircleを返す：

Wolfram Language code: pts = RandomPoint[Circle[{0, 0}, 1, {0, Pi / 2}], 20];
Wolfram Language code: CircularArcThrough[pts]

RegionMemberを使って点の帰属関係を調べる：

Wolfram Language code: reg = CircularArcThrough[{{Sqrt[2], 0}, {1, 1}, {0, Sqrt[2]}}]
Wolfram Language code: RegionMember[reg, {1, 1} ]
Wolfram Language code: RegionMember[reg, {-1, 1} ]

CircularArcThroughは点を通る円弧を与える：

Wolfram Language code: pts = {{Sqrt[2], 0}, {1, 1}, {0, Sqrt[2]}};
Wolfram Language code: CircularArcThrough[pts]

完全な円を得る：

Wolfram Language code: CircleThrough[pts]

RegionFitを使って点の集合にフィットする円を求める：

Wolfram Language code: points = CirclePoints[5];
Wolfram Language code: RegionFit[points, "Circle"]

最初の3点を通る円弧：

Wolfram Language code: CircularArcThrough[Take[points, 3]]

CirclePointsを使って単位円上に等間隔の点を生成する：

Wolfram Language code: pts = CirclePoints[3]

単位円上の点を通る円弧：

Wolfram Language code: CircularArcThrough[pts]
