• n. In geometry: A straight line through two consecutive points (which see, under consecutive) of a curve or surface.
• n. The length cut off upon the straight line touching a curve between the line of abscissas and the point of tangency.
• n. In trigonometry, a function of an angle, being the ratio of the length of one leg of a right triangle to that of the other, the angle opposite the first leg being the angle of which the tangent is considered as the function.
• n. In the clavichord, one of the thick pins of brass inserted in the back ends of the digitals so that the fingers should press them against the strings, and produce tones.
