For the special case one of original equations contains only two unknowns, these two variables can be sampled firstly, and then introduced into the other two 3 - variable equations. the real solutions obtained are spread along the cylindrical contour curve, so that a two dimensional graph which is easy to observe is generated. the corresponding spatial points of intersection are found through the points of intersection of the two curves in this graph
對于方程組中有一個二元方程的特殊情況,還可首先給該二元賦值,然後代入另外兩個三元方程,將求得的實數解沿該二元方程的柱面輪廓線展開,得到便於觀察的二維圖形,通過該兩條交線的交點找到其相應的空間交點。
