Automatically evaluating related cells I've fixed about comparison, and is their a way to do this for all cell, without wrapping in Dynamic explicitly? |

Solve Differential equation system You should use DSolve. RSolve is not for differential equations. |

How can I solve an equation with symbolic coefficients? By Solve Mathematica returns a Root object, which indeed an analytical solution, as I know. And stated in documentation. |

Plotting series solution to the heat equation It produces a plot for me: Wolfram Mathematica 9. I think you mistyped the SUM. The correct is Sum. |

NSolve: Mathematica 9 issue @b.gatessucks: True. Original there was a bunch of user constants. Just a mistyped after == sign. |

A triple sum related question @Chris'ssister: Just N[<expression>, <number of digits>]. And, are you sure summation over j and k is done from i + 1 and j + 1? This sum: Sum[1/(i! j! k!), {i, 1, Infinity}, {j, 1, Infinity}, {k, 1, Infinity}] equals to (e - 1)^3. |

A triple sum related question @Chris'ssister: 1. It was just an assumption why it does not compute nothing. 2. That a function that gives the numerical value of expression, see N. |

A triple sum related question Maybe because it does not have an exact values in terms of $\pi$, $e$ and other known constants or functions. N[Sum[1/(i! j! k!), {i, 1, Infinity}, {j, i + 1, Infinity}, {k, j + 1,
Infinity}]] computes fine and returns 0.122759. |

Calculating error of the approximate formula in calculations I've updated the question. I think this is now much easier to understand. |

Plotting $\omega(k_x, k_z)$ in $(\omega, k)$ plane with assumption of $k^2 = k_x^2 + k_z^2$ I've updated the question, if it isn't clear enough now - I will update further. |

Plotting $\omega(k_x, k_z)$ in $(\omega, k)$ plane with assumption of $k^2 = k_x^2 + k_z^2$ And how should I share code, when copying from Mathematica I get plenty of some strange additions like \FractioBox and \SuperscriptBox? |
