Significats de radius vector en anglès

Airy wrote expressing his interest, and asked for particulars about the radius vector.

They concerned the error of the radius vector.

The angles measured by Struve, reckoned from the radius vector, prolonged towards the sun, are subjoined:

The area covered would always be uniform, because the radius vector would always be uniform in length.

He also now answered quite satisfactorily, but too late, the question about the radius vector sent to him months before.

This result is in perfect harmony with Kepler's Second Law, which states that equal areas are described by the radius vector in equal times.

An important error in the theoretical formulae for Variations of Radius Vector, Longitude, and Latitude, was discovered; some calculations depending on them are cancelled.
