Multisection of a mathematical quantity or figure is division of it into a number of (usually) equal parts. Division of a quantity into two equal parts is known as bisection, and into three equal parts is known as trisection.
The coordinates of the first 
-multisection of a line segment with endpoints given in trilinear coordinates by
