1. Wait... How does this one work? How do you get the red line from the other two? I don't get it.

   (x,y) = m1*(x1,y1) + m2*(x2,y2) (m1 and m2 are constant.)

   EStá genial!! si alguien me mandara algo así entonces sí podría decir eso de _ querido ahora sí que me has conquistado. Pero lo que sí se echa en falta es la diversidad y que algún ejemplo se hiciera con símbolos iguales por que el amor no entiende de sexos.

   你好，请问GGB中如何才能产生画心形红线的效果，我说的不是一次产生轨迹，而是跟随一个点慢慢画出轨迹的效果，在GGB中怎么实现！南京 小虫 。谢谢

   你好，我所知道的方法有兩種：
   1.設定(勾選)動點的 Basic --> Show Trace。
   2.將參數曲線(指令 Curve)的 End Value 設成 Slider 變數。
   兩相比較，後者繪出的曲線較美觀，但耗費較多系統資源。
