Limit:A limit is a fundamental concept in calculus that describes the behavior of a function as it approaches a certain value, such as infinity.
Infinite Series:An infinite series is the sum of an infinite sequence of numbers. It may converge (approach a finite value) or diverge (not approach any specific value).
Inflection Point:In calculus, an inflection point is where the concavity of a curve changes. It can occur at points where functions approach infinity or negative infinity.
