Webbplot nullclines mathematica WebbNullclines, soms ook wel zero-growth isoclines genoemd, zijn verschijnselen die optreden in twee-dimensionale systemen van differentiaalvergelijkingen ′ = (,) ′ = (,). Dit zijn krommen waarlangs het vectorveld geheel horizontaal of geheel verticaal is. Een nullcline is een grens tussen de regio’s waar ′ of ′ van teken wisselen. Nullclines kunnen worden …
WebbI'm struggling with such problem that I need to find fixed points, and then sketch the nullclines,the vector field and a phase portrait. I cannot handle finding fixed points of those two differential equations in one point: dx/dt=2xy dy/dt=y^2-x^2 How to get those fixed points and then sketch this phase portrait? Webbsketch the nullclines and make a qualitative phase diagram. What kind of xed point do you obtain? Answer: Nullclines with _x= 0: x= 0 and y= 0. Nullclines with _y= 0: y= x2. Sketch: The xed point behaves as a saddle point: it is unstable, but it has a stable direction along the y-axis. This is also consistent with the index I= 1 of the xed ...
