Phase line (mathematics) - Wikipedia In this case, a and c are both sinks and b is a source. In mathematics, a phase line is a diagram that shows the qualitative behaviour of an autonomous ordinary differential equation in a single variable, d y d x = f ( y ) {\displaystyle {\tfrac {dy} {dx}}=f (y)} .

An equilibrium of such an equation is a value of x for which F ( x ) = 0 (because if F ( x ) = 0 then x ' ( t ) = 0, so that the value of x does not change). A phase diagram indicates the sign of x ' ( t) for a representative collection of values of x. To construct such a diagram, plot the function F, which gives the value of x '.

PDF 1.5Phase LineandBifurcationDiagrams - University of Utah 30 Example (Phase Line Diagram) Verify the phase line diagram in Figure 15 for the logistic equation y′ = (1 −y)y. Solution: Let f(y) = (1 − y)y. To justify Figure 15, it suffices to find the equilibria y = 0 and y = 1, then apply Theorem 3 to show y = 0 is a source and y = 1 is a sink. The plan is to compute the equilibrium points, then ... Differential Equations - Phase Plane - Lamar University Our equilibrium solution will correspond to the origin of x1x2 x 1 x 2. plane and the x1x2 x 1 x 2 plane is called the phase plane. To sketch a solution in the phase plane we can pick values of t t and plug these into the solution. This gives us a point in the x1x2 x 1 x 2 or phase plane that we can plot. Doing this for many values of t t will ...

PDF Phase Plane Diagrams of Difference Equations in the (u;v) phase plane goes through the origin, so does the transformed linear solutions. (2)an elliptical trajectory in the (u;v) phase plane is transformed to an elliptical trajectory in the (x;y) phase plane. (3)a spiral shaped trajectory in the (u;v) phase plane is trans-formed to a spiral shaped trajectory in the (x;y) phase plane. How do you draw a phase diagram with a differential equation? Now, the ΔH sub is better known, so note that at a phase equilibrium, for some phase transition at constant temperature and pressure, ΔGtr = ΔH tr − T trΔStr = 0, so ΔStr = ΔH tr T tr. Therefore, we obtain the Clapeyron differential equation: dP dT = Δ¯¯¯ ¯H sub T subΔ¯¯ ¯V sub Phase Diagrams for Ordinary Differential Equations | LEEDS ... Each trajectory is described by the equation 3 y 2 = − 2 x 3 + 3 x 2 + C for different values of C. The trajectories above are for C = − 8, − 4, − 0.5, 0, 1, 2, 4 and 6. Here the horizontal x -axis represents the position of a particle and the vertical y -axis represents the velocity of the particle - remember that y = x ˙.

PDF Differential Equations - University of South Florida Phase Diagrams A phase diagram of a di erential equation is a graph of the di erential equation. Usually we have the level of the aluev of the function y on the horizontal axis, and the change in y on the vertical axis. Another important component of a phase diagram are arrows pointing the direction of the movement of y over time.
