Any rule of thumb for converting a simple mathematical expression into a pure function? I like this answer, thanks. Does it make much difference if my input data is {{u},{v}} or {u1,u last,v1,...,v last}? I have other expressions than I one I gave in mind. |

Any rule of thumb for converting a simple mathematical expression into a pure function? Sorry, the formula I typed in is NOT the euclidean distance (some variant) but still my question stands. It is not about getting the unique built-in matching my initial expression. |

Solving a system of equations with conditions related to the number of solutions Thanks, I knew about this way, see my note below that I gave to the answer given by J.M. I implemented in MMA the formula such as it is given in the quoted link where the numerator in the curvature expression is a bit different from yours . Your answer is shorter and very elegant. |

Solving a system of equations with conditions related to the number of solutions There is another way to find the apex of this conic, minimizing the ratio of curvature, for an implicit f(x,y) = 0 ) function thus a more general approach. I never found any textbook where this subject is broached in details and it was only on an internet that I found the relevant link - ann.jussieu.fr/~frey/papers/meshing/… - see 3.1 formula based on gradient and hessian matrices. It was quite mechanical to convert it into MMA but without it a pain in the neck to get this way the apex coordinates.SK |

3- dimensional plot of 2-dimensional systems of differential equations With your solution how you can you store in a table the equations of all the plotted solutions? Is it possible to use the Tooltip function in order to display the specific solutions on the output area? Thanks |
