Limits are just Really, Really, Tiny Flashlights

An intuitive explanation of limits in calculus — using flashlights. This is my submission for the Summer of Math Exposition 4 (SoME4): an attempt to "elucidate" the concept of limits in a way that gives student a solid visual intuition. Topics covered: What a limit is and how it relates to finding the value of a function Holes and jump discontinuities — when the function breaks but the limit still exists Infinite oscillation and why some limits don’t exist (or still do even with infinite oscillation!) How derivatives depend on limits to define instantaneous slope Left-hand and right-hand limits Limits at infinity and how functions behave far away The epsilon–delta definition (aka the flashlight–target definition) Who it's for: High school and college calculus students Math teachers explaining limits visually Anyone preparing for AP Calculus, university calculus, or math contests Viewers interested in SoME4, math visualization, or math education videos Explore It Yourself: Try this Desmos graph to explore the flashlight analogy yourself!   / desmos-graph-for-137755159   Special Thanks: Thanks to openclipart.org for the CC0 clipart used in this video — especially the flashlight!
