This document discusses applications of various conic sections in real life. It begins by defining conic sections as curves derived from slicing a double-napped cone and lists the main types - parabolas, ellipses, circles, and hyperbolas. It then provides examples of applications for each type of conic section, such as parabolas in football trajectories, ellipses in eye shapes and planet orbits, circles in wheels and records, and hyperbolas in sonic booms and lighthouse beams. The document aims to illustrate how conic sections appear frequently in architecture, engineering, and natural phenomena.
