| 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... |
| Is it possible to manipulate the limits in in your table? How can I say to mathematica that I want to stop the evaluation in certain moment (Table)? I was trying to do this F[x_]:=(x - 4) (x - 8) (x) F2[x_] := If[0 |
| Hi I was looking how to operate in just one subelement of a matrix or kind of list, this is what I want: I have the next Matrix: a1 = {{1, 43}, {123, 54}, {124, 78}} I need to operate the first subelement of each element for example if I want... |
| Hi Im trying to obtain the area of the function f(x)=x^3 from 1 to 3, but by aproximation with random points in a rectangle area of [1,3]X[3,27] but I can´t count the points that are inside my function only is this I need the total points that are... |
