The author uses mathematical terms such as "linear" and "vertical" to describe the scene because they provide a precise and visual way to convey the positioning and arrangement of objects or elements in the scene.
By using the term "linear," the author is suggesting that the objects in the scene are arranged in a straight line or a sequence. This helps the reader visualize the order or progression of the objects. For example, if the author describes a linear arrangement of trees, it implies that the trees are positioned one after another in a straight line.
The term "vertical" is used to describe the orientation of the objects in the scene. It indicates that the objects are positioned in an upright manner, perpendicular to the ground or horizontal axis. This term is often used to describe the positioning of tall objects such as buildings, pillars, or trees. For instance, if the author mentions vertical columns in a scene, it suggests that the columns are standing upright.
Using mathematical terms in describing the scene adds precision and clarity to the author's description, allowing the reader to better visualize the arrangement and positioning of objects. It helps create a more vivid and detailed mental image of the scene in the reader's mind.
