ある直線、曲線上を動く点

動点を作りたいと思っています。

動点は最初、鉛直方向または水平方向のみ作成できますよね。

曲線状に動く点や斜め方向に動く点を作り、その動点とある2つの定点とを線分で結び、線分で囲まれた部分のの面積が変化するようなシステムを作りたいのですがどうすれば良いのでしょうか。

If you place a point on a curve, a function, a segment, or whatever geometric object, you can then move it manually along the object it's attached to, or animate it by right clicking on it and selecting `Animation on`.

I don't understand much what you want to get, sorry but automatic translation doesn't help. I'm attaching a sample file to show you a point on a piece of parabola and an area depending on it. Maybe it can gets you inspired about what you want to achieve. (Have a look at the objects definitions in Algebra View)
