What's the difference between chord and secant?

Chord


Definition:

  • (n.) The string of a musical instrument.
  • (n.) A combination of tones simultaneously performed, producing more or less perfect harmony, as, the common chord.
  • (n.) A right line uniting the extremities of the arc of a circle or curve.
  • (n.) A cord. See Cord, n., 4.
  • (n.) The upper or lower part of a truss, usually horizontal, resisting compression or tension.
  • (v. t.) To provide with musical chords or strings; to string; to tune.
  • (v. i.) To accord; to harmonize together; as, this note chords with that.

Secant


Definition:

  • (a.) Cutting; divivding into two parts; as, a secant line.
  • (a.) A line that cuts another; especially, a straight line cutting a curve in two or more points.
  • (a.) A right line drawn from the center of a circle through one end of a circular arc, and terminated by a tangent drawn from the other end; the number expressing the ratio line of this line to the radius of the circle. See Trigonometrical function, under Function.

Example Sentences:
