What's the difference between dichotomy and quadrature?

Dichotomy


Definition:

  • (n.) A cutting in two; a division.
  • (n.) Division or distribution of genera into two species; division into two subordinate parts.
  • (n.) That phase of the moon in which it appears bisected, or shows only half its disk, as at the quadratures.
  • (n.) Successive division and subdivision, as of a stem of a plant or a vein of the body, into two parts as it proceeds from its origin; successive bifurcation.
  • (n.) The place where a stem or vein is forked.
  • (n.) Division into two; especially, the division of a class into two subclasses opposed to each other by contradiction, as the division of the term man into white and not white.

Quadrature


Definition:

  • (a.) The act of squaring; the finding of a square having the same area as some given curvilinear figure; as, the quadrature of a circle; the operation of finding an expression for the area of a figure bounded wholly or in part by a curved line, as by a curve, two ordinates, and the axis of abscissas.

  • (a.) The integral used in obtaining the area bounded by a curve; hence, the definite integral of the product of any function of one variable into the differential of that variable.
