...performed exactly in the same number of days. It has been found, by La Place, that "the epoch (ot.mean **longitude) of the first satellite, minus three times that of the second, plus** two times that of the third, is exactly equal to a semicircle, or 180 degrees." From this it follows,... | |

...more extraordinary than the preceding ; which consists in this, that the mean longitude of the first, **minus three times that of the second, plus twice that of the third,** is constantly equal to two right angles. There is the ratio of infinity to one, that this equality... | |

...attraction, rendered this ratio rigorously exact, and it has moreover made the mean longitude of the first, **minus three times that of the second, plus twice that of the third,** equal to a semi-circumference. At the same time, it gave rise to a periodic inequality, which depends... | |
