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 function's graph at that point. Learn how we define the derivative using limits. Learn about a bunch of very useful rules (like the power, product, and quotient rules) that help us find ...
And this is a fine conceptual understanding of limits, and it really will take you pretty far, and you're ready to progress and start thinking about taking a lot of limits. But this isn't a very mathematically-rigorous definition of limits. And so this sets us up for the intuition.
Worked example: Derivative from limit expression. Practice: Derivative as a limit. The derivative of x² at x=3 using the formal definition. The derivative of x² at any point using the formal definition. Finding tangent line equations using the formal definition of a limit. Next lesson.
Formal definition of the derivative as a limit. The derivative of function f at x=c is the limit of the slope of the secant line from x=c to x=c+h as h approaches 0. Symbolically, this is the limit of [f(c)-f(c+h)]/h as h→0. Created by Sal Khan. This is the currently selected item.

You might recognize, this is one of the definitions of a derivative. This is one of the definitions of a derivative. This right over here would be f prime of two, the derivative at x equals two is equal to the limit as x approaches two of all of this business. There's other ways to express a derivative as a limit but this is one of them.

The limit definition of the derivative is used to prove many well-known results, including the following: If f is differentiable at x 0, then f is continuous at x 0 . Differentiation of polynomials: d d x [ x n] = n x n − 1 . Product and Quotient Rules for differentiation.

Finding tangent line equations using the formal definition of a limit. This structured practice takes you through three examples of finding the equation of the line tangent to a curve at a specific point. Once we've got the slope, we can find the equation of the line. This article walks through three examples.
