| 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,... |
| As I said technically you do not need to specify k and m, if you use the following trick: ContourPlot[p^2/((p^2 - k^2) (p^2 + m^2)) /. k -> 4, {p, -10, 10}, {m, -10, 10}, Frame -> False, ContourStyle -> Opacity[0.02] , ImagePadding ->... |
| A different "integration by points" method is (3-1) Mean[RandomReal[{1, 3}, 100000]^3] which is sort of a mean value theorem approach. |
