Conical curve is the focus and difficulty of middle school mathematics, and it is also a hot spot of college entrance examination. Because it has rich connotations, it is closely related to the real life; many excellent application problems are generated by the combination of solutions; this article discusses several solutions from the knowledge structure. The solution to the problem is for the reader’s reference. 1 Application examples related to straight lines Example 1 As shown in Figure 1, the two straight segments of the river bank AB and AC meet at A, and the M at BAC is the hydrological station.
