If you can find a better way of writing the math below than just plain text, please do.)*
I have a vector field $V: R^2 \to R^2$ and I would like to find $f:(-\epsilon,\epsilon) \to R^2$, for some small $\epsilon>0$, such that $f(0)$ is a given point and $f'(t) = V(f(t))$.

https://ask.sagemath.org/question/10650/integral-curves-in-sage/?answer=15601#post-id-15601Have a look at the sagebook "[Calcul mathÃ©matique avec Sage](http://dl.lateralis.org/public/sagebook/sagebook-web-20130530.pdf)" (in french) at page 87.Thu, 24 Oct 2013 12:28:29 +0200https://ask.sagemath.org/question/10650/integral-curves-in-sage/?answer=15601#post-id-15601
