Webster (1913) Definition: Du"pli*cate, a. [L. duplicatus, p. p. of duplicare
to double, fr. duplex double, twofold. See Duplex.]
Double; twofold.

Duplicate proportion or ratio (Math.), the proportion or
ratio of squares. Thus, in geometrical proportion, the
first term to the third is said to be in a duplicate ratio
of the first to the second, or as its square is to the
square of the second. Thus, in 2, 4, 8, 16, the ratio of 2
to 8 is a duplicate of that of 2 to 4, or as the square of
2 is to the square of 4.
