  1. Limits intro (video) | Limits and continuity | Khan Academy

    In this video, we learn about limits, a fundamental concept in calculus. Limits help us understand what a function approaches as the input gets closer to a certain value, even when the function is undefined …

  2. Formal definition of limits Part 1: intuition review - Khan Academy

    Discover the essence of limits in calculus as we prepare to dive into the formal definition. Enhance your understanding of this fundamental concept by reviewing how function values approach a specific limit …

  3. Limits intro (article) | Khan Academy

    Limits describe how a function behaves near a point, instead of at that point. This simple yet powerful idea is the basis of all of calculus.

  4. Limits and continuity | AP®︎/College Calculus AB - Khan Academy

    Limits describe the behavior of a function as we approach a certain input value, regardless of the function's actual value there. Continuity requires that the behavior of a function around a point …

  5. Definite integral as the limit of a Riemann sum

    The definite integral of a continuous function f over the interval [a, b] , denoted by ∫ a b f (x) d x , is the limit of a Riemann sum as the number of subdivisions approaches infinity.

  6. Limits and continuity | Calculus 1 | Math | Khan Academy

    Formal definition of limits (epsilon-delta) Learn Formal definition of limits Part 1: intuition review Formal definition of limits Part 2: building the idea

  7. 𝑒 as a limit (video) | Logarithms | Khan Academy

    More succinctly, we can say that the limit of 𝑓 (𝑥) as 𝑥 tends to ∞ is 𝑒. Essentially, the limit helps us find the value of a function 𝑓 (𝑥) as 𝑥 gets closer and closer to some value. You will learn more about limits and a …

  8. Derivative as a limit (practice) | Khan Academy

    Write derivatives of functions as limit expressions.

  9. Formal and alternate form of the derivative - Khan Academy

    Discover the two methods for defining the derivative of a function at a specific point using limit expressions. In this video we'll explore the standard form and alternate form, enhancing our …

  10. Formal definition of limits Part 4: using the definition

    Explore the epsilon-delta definition of limits in calculus, as we rigorously prove a limit exists for a piecewise function. Dive into the process of defining delta as a function of epsilon, and learn how to …
