How do you use the gradient to find $n$? @Walter, whenever $x^2 + y^2 < 1$ it represents a radius, but that's not a helpful way of thinking about it in general. In this particular case, your surface $C$ is a hemisphere of radius 1. |

How do you use the gradient to find $n$? @Walter, what is your definition of $z$? Given that, what can you conclude about $\sqrt{x^2 + y^2 + z^2}$? |

Finding the mid-point of a B-spline curve. It's worth adding that "the mid-point" of a Bézier curve is ambiguous (the point $t=0.5$ or the point which splits the curve length equally), but that due to the symmetry of this particular case the two must coincide. |

Finding the mid-point of a B-spline curve. @bubba, given the context, "B spline" without further qualification can safely be assumed to mean uniform non-rational B-spline. |

Possible Playable Chords on a Guitar What is a "combination of at least 3 possible notes"? Does that mean that 3 to 6 strings are strummed? And does your definition of "chord" implicitly require concordance? |

Spherical geometry - relating angles of lunes and segments of great circles It might be simpler to define $\varphi$ as the angle $NC\frac{A+B}2$ where $N$ is the pole. |
