Abstract This paper considers osculating algebraic curves of degree
... This distribution that we just defined is actually the main character of this paper. Most of the results that were mentioned above can be reformulated in terms of XA1 and ω, but first we need to understand what extaticity means in these terms. Besides ω there is a field of directions (v) in XA1 that ...

2.1 Measures of Relative Standing and Density Curves
... These graphs represent the shape of a Normal curve. The area of the portion of the histogram on the left is approximately equal to the area of the portion under the density curve at the same point. Density curve is an approximation that is easy to use and accurate enough for practical use. Measuring ...
