PROBLEM
Prob"lem, n. Etym: [F. problème, L. problema, fr. Gr. 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.)
Definition: 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.
