R³, or "R cubed," refers to a three-dimensional space in mathematics and geometry. It represents all possible points in a space defined by three axes: the x-axis, y-axis, and z-axis. Each point in R³ can be described using three coordinates, such as (x, y, z), which helps in visualizing and solving problems in various fields, including physics and engineering. In practical terms, R³ is essential for understanding the physical world around us. For example, when designing a building or modeling the trajectory of a rocket, engineers use R³ to ensure accuracy and efficiency. This three-dimensional framework allows for a better grasp of complex structures and movements.
