Price $y$ of Russian rouble, measured in the USA cents, versus time $x$:

Data by https://www.mataf.net/en/currency/converter-USD-RUB available for 29 November 2014‎ (thick green line),

the lineal approximation of the data available 2014.10.27 (thin black straight line), and

the approximation Arc, made 2014.11.29 (thick ping arc):

$\mathrm{Arc}(x) = .01 \sqrt{(a+x)(b-x)}$

with $a=471$ и $b=123$.

At the specific choice of ratio of the scale of ordinate axis to that of the abscise axis, approximation Arc appears as arc of the perfect circle. In order to stress this, this arc is a little bit extended below the abscissa axis (to values that would correspond to negative branch of the square root). This approximation suggests imaginary values of rouble for time $x>132$.

Basically, graphic is the same, as the image from 2014.11.29, loaded as http://mizugadro.mydns.jp/t/index.php/File:RubleArc.png

The difference is, that a little bit more space at the left to provide the same range with the later figure http://mizugadro.mydns.jp/t/index.php/File:2015Arc.png, that figure shows that the good agreement of this approximation takes place also for the extended experimental data, since the beginning of year 2014, and more space is necessary.

This image is used as figure 1 in the article and, perhaps, the ubldated versions of that file.

that is supposed to be basically the same as ,

but needs some TORIfication at the uploading.
