FORMULA
, a theorem or general rule, or expression, for resolving certain particular cases of some problem, &c. So (1/2)s + (1/2)d is a general Formula for | the greater of two quantities whose sum is s and difference d; and (1/2)s - (1/2)d is the Formula, or general value, for the less quantity. Also √(dx - x2) is the Formula, or general value, of the ordinate to a circle, whose diameter is d, and absciss x.
