Solving physics problems is often done superficially, without making an in-depth analysis of the results obtained, limiting itself only to determining the numerical values of some physical quantities. In order to analyze the results obtained after solving physics problems and to more deeply understand the essence of the phenomena that take place, a graphic representation of the obtained results is often necessary. In this paper, we present examples of solving different problems from physical systems for which the effect of bistability occurs. We use the graphical method to analyze the results obtained. We mention that the results presented in this paper are suited for teaching undergraduate students.

解决物理问题往往是肤浅的，没有对得到的结果进行深入分析，只限于确定一些物理量的数值。为了分析解决物理问题后得到的结果，更深入地理解所发生现象的本质，常常需要对所得到的结果进行图形表示。在本文中，我们展示了解决物理系统中出现双稳态效应的不同问题的示例。我们使用图形方法来分析获得的结果。我们提到，本文中提出的结果适用于教授本科生。
