Differentiating space curves @Artes: I hadn't seen that before. But I'd rather not redefine tangent and normal for every curve I might be interested in. |

How to make a plot of function over 24 orders of magnitude? As far as I can tell, the asker wants the point $(d, 0.0000697)$ to be visible on the plot, so this does not answer the question. |

Mystified by inability to find info to do what seems really basic ...I don't understand why you don't put the expressions into multiple input cells? |

How to create new “person curve”? Given that the coefficients of $t$ inside the sinusoids are 1, 2, 3, ..., this is probably just the Fourier representation of a parametric curve. I'd guess they manually traced the curve as a polygon, took the discrete Fourier transform, and kept just enough of the lowest-order modes to make the curve look right. See also: Ptolemy and Homer (Simpson). |

Problem with SphericalPlot3D plotting @chris: Oh, that. Yeah, that makes sense. Silly me. |

Problem with SphericalPlot3D plotting @chris: Unless the editor is different from the notebook interface, that doesn't work for me. Whether it's an input or output cell, whenever I copy a θ it pastes as \[Theta] outside Mathematica. |

Problem with SphericalPlot3D plotting Oh well, I pasted them in from Character Map. Hope I didn't make a mistake somewhere. |

Problem with SphericalPlot3D plotting @Mr.Wizard, I don't think it's a duplicate. That question is about colouring the plot; this one is about parts of the desired plot not showing up at all. Unless there's some subtle property of Mathematica I'm missing that makes these the same thing, which, given that Mathematica is sufficiently complicated, is a possibility I won't dismiss... |

Problem with SphericalPlot3D plotting Is there an easy way to replace the escaped characters with their Unicode equivalents? I searched on meta but only found rcollyer saying they would do this, but not how to do so. |

Regionplot with Boole - with more than dimension number of variables Three equations in four variables will give you, generically, a one-dimensional solution space, which will project to a curve in 3D. This looks like it's going to be tricky; certainly RegionPlot3D doesn't do curves. |
