In purpose to calculate the numerical coordinates data of five species of curves as shown in Fig.3, a C++ program originated from Eq.(2) is given by .

In the last, the expression of Eq.(1) in the orthogonal coordinates is led to the follows.
. (3)
[General expression] It is reported from
Mr. Yasuyuki ASAI that the above equation is rewritten from the following general expression.
. (4)
If the constants in Eq.(4) is replaced as , Eq.(4) leads to Eq.(1) in this page. On the other hand, if the constants in Eq.(4) is replaced as , Eq.(4) leads to the first equation in the page of
Mr. Yasuyuki ASAI and leads to Eq.(1) in ouranother page. In another speaking, it is recognized that the egg shaped curve in this page is the same as that in the page of Mr. Suugaku-Dokusyuu-Juku Jukuchou and the analyses have been performed in the different ways each other. Here, we appreciate his suggestion.
