Four ways to explore the number of intersections between line segments and curves 430040 Wuhan Dongxihu Wujiashan No. 1 Middle Gandhavanga The issue of the number of intersection points between line segment and quadratic curve is an important topic of analytical geometry. There are two popular conventional solutions: one is to solve the mixed group; the other is to turn this question into the discussion of the real root distribution of the quadratic equation about x or y, and Mu Wen then introduces four kinds of spirits...
