Solving a system of equations using subscripted variables @user6941 Everything's hard in the beginning :). |

Solve with v9 (issues with Subscript, Overscript, Superscript etc) I just want to add that, this isn't a v9 issue, it exists in my v8 too, and I think it can also be reproduced in earlier version. |

What is the correct syntax for setting up a simulation using a system of ODEs? @user6895 Try Clear["`*"] first… |

Manipulating output from Solve Well, to be honest, I can't explain this clearly, the only thing I know is that f[H1_,H2_] := Evaluate@sol1[[1,1]] will also work. In fact, I used to ask a similiar question(See the first two sample I gave there) but maybe that question is a little messy, so I don't get a very good answer for this part. I suggest you to post a new question if you want to get a better understanding for this. |

Putting NDSolve into ParametricPlot The reason is just, you use p0 = 1 in unforced while actually you use p0 = 0 in the last two lines… |

Removing zero values from ordered pairs I've added a snapshot to my answer. It seems that {_, 0} | {0, _} and {a_, 0} | {0, a_} are different… |

Removing zero values from ordered pairs Well, not really. The fastest seems to be DeleteCases[list, {_, 0} | {0, _}]. |

Manipulating output from Solve Manipulate requires explicitly stating the dependent variables, then, why not explicitly stating the dependent? I guess something like f[H1_, H2_]=sol1[[1, 1]]; g[H3_, H4_]=sol2[[1, 1]]; Manipulate[ContourPlot[f[H1, H2] - g[H3, H4], {H1, a, b}, {H2, c, d}], {H3, e, f}, {H4, g, h}]
will work. |
