解釋
餘弦圓-
It builds a relative coordinates based on the jumping - off point of circular interpolation as its origin, caculates the sine and cosine of the angle formed by x axis and the line which connects the origin and the centre of the circle, then gets the coordinates of the centre in the relative coordinates, and enduces a uniform fomula, which is easy to program in computer
摘要用圓弧插補起點作為相對坐標系原點,連接圓弧起點和圓心,求出該連接線和相對坐標x軸的夾角的正餘弦值,由此解出圓心在相對坐標系的坐標,並得到一個統一的計算公式,易於計算機編程實現。
