Subduplicate of the triplicate; -- a term applied to ratios; thus, a and a′ are in the sesquiplicate ratio of b and b′, when a is to a′ as the square root of the cube of b is to the square root of the cube of b′, or a:a′::√b3:√b′3.(Math.)“The periodic times of the planets are in the sesquiplicate ratio of their mean distances.” — Sir I. Newton.
