The Vietnamese word "hoành độ" refers to the term "abscissa" in English. It is a mathematical term used in the context of a coordinate system, particularly in a Cartesian coordinate system.

Explanation:

• Definition: The "hoành độ" represents the horizontal distance of a point from the vertical axis (y-axis) in a two-dimensional graph. It indicates how far left or right a point is from the origin (the point where the x-axis and y-axis intersect).

Usage Instructions:

• "Hoành độ" is typically used when discussing graphs, coordinates, or geometry. You would encounter this term in math classes, especially when plotting points or lines on a graph.

Example:

• In a coordinate plane, the point (3, 2) has a hoành độ of 3. This means it is located 3 units to the right of the y-axis.

Advanced Usage:

• In more advanced mathematics, "hoành độ" can be used when discussing functions, transformations, or even in calculus when dealing with the concept of limits and continuity on a graph.

Word Variants:

• The term "hoành độ" is usually used in its standard form, but you might encounter related terms such as:
  • "tọa độ" (coordinates) which includes both hoành độ and tung độ (the vertical component, or ordinate).

Different Meaning:

• "Hoành độ" is a specific term in mathematics, so it does not have other meanings outside of this context.

Synonyms:

• In mathematical contexts, there are no direct synonyms for "hoành độ," but you may come across terms like "trục x" (x-axis) when discussing the axis on which the abscissa is measured.
