2021-05-04 14:55:46 +0100 | marked best answer | Geometry math I can't wrap my brain around this today. If you have hexagons attached to the edges of a pentagon in 2D, how far must you rotate two of the hexagon around their common edge with the pentagon, to bring their common edge into alignment? That is, how do you calculate it. It might be squares around a triangle, or pentagons around a square etc. |

2021-05-02 18:41:31 +0100 | marked best answer | How to create a 3D plot of a parametric equation that requires 3 variables? I'm try to plot (one nappe of) a cone using the parametric formula (from https://en.wikipedia.org/wiki/Cone#Eq...) : where s , t , u range over [ 0 , θ ), [ 0 , 2 π ) , and [ 0 , h ], respectively. I tried: but it took the third range as plot_points. Then I tried: attempting to let t do double duty as s also. It plots, but produces: Which is pretty, but no cigar. How can I achieve my goal? Update: I found another formulation of the equation on the web and tried: And got: Ditto on the absence of stoggies. |
