Vanishing

Vanishing fraction — a fraction which reduces to the form <frac:0_0/ for a particular value of the variable which enters it, usually in consequence of the existence of a common factor in both terms of the fraction, which factor becomes 0 for this particular value of the variable.

Vanishing line — the intersection of the parallel of any original plane and the picture; one of the lines converging to the vanishing point.

Vanishing point — the point to which all parallel lines in the same plane tend in the representation.

Vanishing stress — stress of voice upon the closing portion of a syllable.
