hyperbola
[haษชหpษหrbษlษ ]
Definition
mathematics shape
A hyperbola is a type of smooth curve lying in a plane defined by its geometric properties or equations. It is one of the conic sections defined by intersecting a cone with a plane. Hyperbolas are characterized by their two separate branches, which are mirror images of each other. They arise in various contexts such as physics, engineering, and data analysis, particularly where the relationship between two variables is not linear.
Synonyms

Origin of 'hyperbola'
The word 'hyperbola' originates from the Greek word 'hyperbolฤ', meaning 'excess' or 'overflow'. The term was used in mathematics to describe one of the conic sections discovered by ancient Greek mathematicians, notably by Apollonius of Perga, around 200 BC. The concept of the hyperbola continued to evolve over centuries, gaining significance in various fields of study such as physics and engineering. Hyperbolas were intriguing due to their unique properties and applications, particularly in the study of trajectories and optical systems. The mathematical study of hyperbolas has been further expanded in the modern era, making them an essential concept in high school and college level mathematics.
