Abscissa and ordinate a parametric equation. Used in this way, the abscissa can be thought of as a coordinate-geometry analog to the independent variable in a mathematical model or experiment (with any ordinates filling a role analogous to dependent variables). Abscissa and ordinate In mathematics, the abscissa (; plural "abscissae" or "abscissæ" or "abscissas") and the ordinate are respectively the first and second coordinate of a point in a coordinate system. The abscissa of a point is the signed measure of its projection on the primary axis, whose absolute value is the distance between the projection and the origin of the axis, and
Graph of a function should be taken into account. The graph of a function on its own doesn't determine the co-domain. It is common to use both words, function and graph of a function, since even if considered the same object, they indicate viewing it from a different angle. Given a mapping formula_1, in other words a function formula_2 together with its domain formula_3 and co-domain formula_4, the graph of the mapping is the set which is a subset of formula_6. The graph of the function formula_2 is the same set formula_8, which is, in the abstract definition of a function, the same as
