Hello I would like to make a Poincare map solving 4 no linear differential equations, I saw a tutorial in mathematica which im doing the same steps, but I want to solve this equations with the restriction that $ \phi 1 (t) = 2 \pi $ . When I use... |

Almost! The graph is not as important, the important thing is the value that I want no to obtain near de critical point, for example in your reply in FindMaxium you put limits from 0 to 9 , the 0 is ok, but instead of 9 I want that the evaluation... |

Thank you very much guys, I' have completed what I wanted and I succeeded by the way of Peter Fleck but applying a function on it: In[945]:= c2na Out[945]= {{3.89323, 292.79}, {3.86742, 302.68}, {3.84187, 312.64}, {3.8158,... |

I think the function you want to plot consist in three variables, so plot is as follows Plot[f[x,y,z],{x,xmin,xmax},{y,ymin,ymax},{z,zmin,zmax}] in your case the vairables are m,k,p but maybe one of them is constant or two of them. you know If... |

Thanks!, that´s nice model or another way to do it, the problem is that I need with the model given in my request, so i tried putting only your Count in my model and failed |
