Cutting a simple geometry in halfLogin
53B3053C50We develop the Lorentzian geometry of a crooked halfspace in 2+1-dimensional Minkowski space. We calculate the affine, conformal and isometric automorphism groups of a crooked halfspace, and discuss its stratification into orbit types, giving an explicit slice for the action of the ...
in reply to Kent1Cooper 11-26-2020 03:23 AM From your answer I got only 1 new point,i.e,: a circle passes through the mid-point of two lines. I've send screenshot of arc halfwidth figure and it's geometry. 1. Radius of the mid-point arc ? → R is...

The 'ball' scene was rendered in Python using a Phong BRDF, which is not available in Blender. The geometry is a unit sphere, and the two rough "bands" are at (abs(x) < 0.15) || (abs(y) < 0.15). The rough bands have a Phong exponent of 50, with the rest set to 500. Th...

Scientists and policymakers need satellite data to understand and address climate change. Yet data from more than half of unclassified Earth-observing satellites is restricted in some way, rather than shared openly.
答案解析:根据advanced mathematics定位到这两句话。题干中问的是理解高等数学只需要有限的什么知识。而algebra, geometry和trigonometry都是不需要的。a little又与a limited of同义替换,由此确定arithmetic为答案。 第37题答案:intuitive 对应原文:A部分第2段:to appreciate the beauty of mathematics, and to become ...
