Symbol 38:4

3802c

38:4 · With the same structure as the Taurus sign entry above, this sign means variation in astronomy and mathematics. The moon's variation is the moon's periodically accelerated orbital speed caused by the fact that the sun's gravitational pull sometimes works against and sometimes with the orbital movement of the moon around the earth. The sign is sometimes used in mathematics as a synonym with 2665.
