Demonstration


Definition:

  • (n.) The act of proving by the syllogistic process, or the proof itself.
  • (n.) A course of reasoning showing that a certain result is a necessary consequence of assumed premises; -- these premises being definitions, axioms, and previously established propositions.

  • (n.) Repetition of a theme or melody with fanciful embellishments or modifications, in time, tune, or harmony, or sometimes change of key; the presentation of a musical thought in new and varied aspects, yet so that the essential features of the original shall still preserve their identity.
  • (n.) One of the different arrangements which can be made of any number of quantities taking a certain number of them together.
