In Algebra, a proposition stating the quality of two quantities by placing the sign () between them. The general rule for the solution of questions producing simple equations, is to express the unknown quantities by letters, and the relations between the known and unknown, or, as they are called, the conditions, by equations, which, being resolved, give the answer. Example:-If the question is concerning two numbers, they may be called and y, and the conditions from which they are to be investigated must be expressed by equations, thus: If it be required that the sum of two numbers sought be 60, that condition is thus expressed, æ+y=60. If their difference must be 24, then -y=24. If their product is to be 26, then xy=96. If their quotient is to be 6, then =6. Fquation of a curve, an equation expressing the nature of a curve, the relation between an absciss and a corresponding ordinate, or the relation of their fluxions. Equation of time, in Astronomy and Chronology, the reduction of the apparent time or motion of the sun, to equable, mean, or true time. In Astronomy, the small connections which must be added or substracted from the results of the EQUATOR-EQUIDIFFERENT. simple law, characteristic of all the heavenly motions, are termed equations, as in the equation of time, equation of the equinoxes, equation of the centre, and annual equation. Equation of payments, in Arithmetic, finding the time to pay several debts at once, which are due at different dates, and bearing no interest till after the time of payment, so that no loss shall be sustained by the parties making or receiving payment. EQUATOR, e-kwa'tur, s. (Equator, Lat.) A great circle of the terrestrial globe, equidistant from its poles, and dividing it into two equal hemispheres; one north and the other south. EQUATORIAL, e-kwa-to're-al, a. Pertaining to the equator. Equatorial, universal, or portable observatory, is an instrument intended to answer a number of useful purposes in practical astronomy, independent of any particular observatory. EQUERY, ek'kwer-re, or e-kwer'e, s. (ecuyer, Fr.) An officer of princes, who has the care and management of his horses; a stable or lodge for horses. EQUES, e'kwis, s. (Latin, a horseman.) The name given to the equestrian order among the Romans. The Equites constituted the second degree of nobility, succeeding the senators in point of rank; they required to be possessed of 400 sestertia before being admitted into the order. Each had a horse given and kept at the public charge; as a soldier, he was obliged to serve in the wars, and wore a ring given him by the state.-A genus of fishes, having, as in Umbrina, the snout thick, obtuse, and truncate; caudal fin round and inclined upwards; two dorsal fins, the first short and falcate, the second long; ventral as large as the pectoral; anal very short and oval; fins scaly at the base: Family, Chaetodonidæ. EQUESTRIAN, e-kwes ́tre-an, a. (equester, from equus, a horse, Lat.) Relating to horses or horseinanship; performed with horses; being on horseback; skilled in horsemanship; representing a person on horseback; celebrated by horse races; belonging to knights. Among the ancient Romans, the equestrian order was the order of knights, equites, also their troopers or horsemen in the field. civil life, the knights stood contradistinguished from the senators in the field from the infantry. -See Eques. ་ a In EQUIANGULAR, e-kwe-ang'gu-lur, a. (œquus, equal, and angulus, an angle, Lat.) In Geometry, consisting of, or having equal angles, applied to figures whose angles are all equal, such as a square, an equilateral triangle, a parallelogram. EQUIBALANCE, e-kwe-bal'ans, s. (œquus, and bilanx, Lat.) Equal weight;-v. n. to have equal weight with something. EQUICRURAL, e-kwe-kroo'ral,) a. (aquus, and crus, EQUICRURE, e-kwe-kroor', leg. Lat.) Having legs of equal length; having equal legs, but longer than the base; isosceles. EQUIDIFFERENT, e-kwe differ-ent, a. Having equal differences; arithmetically proportional. Equidifferent numbers, in Arithmetic, are of two kinds. 1. Continually equidifferent is when, in a series of three numbers, there is the same difference between the first and the second, as there is between the second and third-as, 3, 6, 9. And 2. Discretely equidifferent is when, in a series of four numbers or quantities, there is the same difference between the first and second as there is |
