  2. Derivatives: definition and basic rules | Khan Academy

    The derivative of a function describes the function's instantaneous rate of change at a certain point. Another common interpretation is that the derivative gives us the slope of the line tangent to the …

  3. Formal definition of the derivative as a limit - Khan Academy

    Discover how to define the derivative of a function at a specific point using the limit of the slope of the secant line. We'll explore the concept of finding the slope as the difference in function values …

  4. 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 …

  5. Differentiation: definition and basic derivative rules | Khan Academy

    The derivative of a function describes the function's instantaneous rate of change at a certain point - it gives us the slope of the line tangent to the function's graph at that point.
