lascissa

Lascissa is the x-coordinate of a point in the Cartesian plane, commonly referred to as the abscissa in mathematical notation. For a point P with coordinates (x, y), the lascissa is the value x, representing the signed distance from the origin to the vertical projection of P onto the x-axis. It is positive to the right of the origin and negative to the left.

In Italian usage, the x-coordinate is usually called ascissa, while lascissa appears as a variant in some

The lascissa plays a central role in coordinate geometry. It determines the horizontal position of a point

In three-dimensional space, coordinates are written as (x, y, z). Here x remains the lascissa, representing the
