In the previous section, we show how to provide a qualitative information about solution curves to a first order differential equation using direction fields. We first start with adding solution curves to the direction fields. Their applications will be clear from presented examples here. \) Besides, Mathematica also offers their variations: Plot = Plot[x = f(x,y), \) a user needs to set 1 for the firstĬoordinate and f for the second one, so making the vector input Most differential equations do not have solutions that can be written in elementary form, and even when they do, the search for formulas often obscures the central question: How do solutions behave? One of the ways to trap solution curves is to determine their boundaries-called fences. Understand the features of the solution and its behavior. A phase portrait must include enough information to The content of a phase portrait will varyĭepending on the problem or differential equations and the behavior of It can be difficult to give a strict definition of phase portraitsīecause there are no strict, consistent rules for what a phase Have distinct trajectories, and their varying paths can be represented by Different fish at different positions will Helpful way to think of phase portraits is to imagine fish swimming in Visualizing the long run behaviors of solutions to differential equations.
Some typical solution curves that are needed to determine some otherįeatures of streamlines, such as the bounds (or fences), sepatratrix,Īnd other similar properties within varying domains. A phase portrait is a graphical tool that consists of Theĭetailed features can only be obtained if we observe the phase Shows arrows on a plot indicating the direction of streamlines. Is not detailed on the behavior of specific solutions, as it only Plotting either a list of vectors or lines.
