Limit Definition Of The Derivative Math
1 4 limits and the derivative definition.
Limit definition of the derivative math. F x lim h 0f x h f x h. Note that we replaced all the a s in 1 1 with x s to acknowledge the fact that the derivative is really a function as well. By cancellng out h s. F x lim h 0 f x h f x h f x lim h 0 f x h f x h find the components of the definition.
F x lim h 0 m x h b mx b h. Symbolically this is the limit of f c f c h h as h 0. F x lim h 0 f x h f x h. The following problems require the use of the limit definition of a derivative which is given by they range in difficulty from easy to somewhat challenging.
F x h f x h. 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. So for the posted function we have. In this case we write.

The derivative of f x f x with respect to x is the function f x f x and is defined as f x lim h 0 f x h f x h 2 2 f x lim h 0. By cancelling out mx s and b s lim h 0 mh h.
Remember that the limit definition of the derivative goes like this. By multiplying out the numerator lim h 0 mx mh b mx b h. We say that the number l is the of g x as x approaches a provided that g x can be made arbitrarily close to l for all x sufficiently close but not to a. In addition the limit involved in the limit definition of the derivative is one that always generates an indeterminate form of 0 0.
