Problem \Prob"lem\, n. [F. probl[8a]me, L. problema, fr. Gr. [?] anything thrown forward, a question proposed for solution, fr. [?] to throw or lay before; [?] before, forward + [?] to throw. Cf. {Parable}. ] 1. A question proposed for solution; a matter stated for examination or proof; hence, a matter difficult of solution or settlement; a doubtful case; a question involving doubt. --Bacon. 2. (Math.) Anything which is required to be done; as, in geometry, to bisect a line, to draw a perpendicular; or, in algebra, to find an unknown quantity. Note: Problem differs from theorem in this, that a problem is something to be done, as to bisect a triangle, to describe a circle, etc.; a theorem is something to be proved, as that all the angles of a triangle are equal to two right angles. {Plane problem} (Geom.), a problem that can be solved by the use of the rule and compass. {Solid problem} (Geom.), a problem requiring in its geometric solution the use of a conic section or higher curve. |
