## What does it mean if a derivative is defined?

The definition of the derivative is the slope of a line that lies tangent to the curve at the specific point. The limit of the instantaneous rate of change of the function as the time between measurements decreases to zero is an alternate derivative definition.

## What are the two definitions of a derivative?

The definition of the derivative can be approached in two different ways. One is geometrical (as a slope of a curve) and the other one is physical (as a rate of change).

**Where is derivative undefined?**

If there derivative can’t be found, or if it’s undefined, then the function isn’t differentiable there. So, for example, if the function has an infinitely steep slope at a particular point, and therefore a vertical tangent line there, then the derivative at that point is undefined.

### What is the limit definition of derivative?

Limit Definition of the Derivative. We define the derivative of a function f(x) at x = x0 as. f (x0) = lim. hâ†’0. f(x0 + h) âˆ’ f(x0)

### What is the limit definition of a derivative?

**When dy dx is undefined?**

dy/dx is undefined when -3t2 = 0. So, t = 0.

#### What does a derivative of 0 mean?

The first derivative of a point is the slope of the tangent line at that point. When the slope of the tangent line is 0, the point is either a local minimum or a local maximum. Thus when the first derivative of a point is 0, the point is the location of a local minimum or maximum.

#### What is the limit definition of a derivative mean?

Since the derivative is defined as the limit which finds the slope of the tangent line to a function, the derivative of a function f at x is the instantaneous rate of change of the function at x.

**What is the limit in calculus?**

In Mathematics, a limit is defined as a value that a function approaches the output for the given input values. Limits are important in calculus and mathematical analysis and used to define integrals, derivatives, and continuity.
