center-corner-vector-angle

angle between the center and each corner of a regular minimal polygon in n dimensions

example

var findAngle = require('center-corner-vector-angle')

for (var n = 2; n <= 20; n++) {
    console.log(n + ' => ' + findAngle(n));
}

methods

var findAngle = require('center-corner-vector-angle')

var angle = findAngle(n)

Return the angle in radians for the regular polygon with n points in n dimensions.

In 2 dimensions, this is the angle between the centerpoint of an equilateral triangle and 2 of the other points, which is pi/3.

install
