WebIf energy (say, in the form of light) is emanating from the origin, its intensity will be the same at all points equidistant from the origin. That is, at any point on the surface of a sphere centered at the origin, the intensity should be the same. Therefore, the … WebHe is right in that from 0 - pi/2 for S and T only sketches 1/4th of the outer surface for 1/4th of the circumference, or 1/8th of the total torus surface. But on the right diagram he starts shading this parametrization on the y-axis while the left he starts from the x-axis. ... I find it helpful to start by thinking of a more familiar circle ...
