# What is the second derivative used for?

The second derivative is the rate of change of the rate of change of a point at a graph (the “slope of the slope” if you will). This can be used to find the acceleration of an object (velocity is given by first derivative).

## What is the second derivative used for?

The second derivative is the rate of change of the rate of change of a point at a graph (the “slope of the slope” if you will). This can be used to find the acceleration of an object (velocity is given by first derivative).

## What happens when a double derivative is zero?

Since the second derivative is zero, the function is neither concave up nor concave down at x = 0. It could be still be a local maximum or a local minimum and it even could be an inflection point. Let’s test to see if it is an inflection point.

## Where is the derivative equal to zero?

It is because the derivative is a measure of the slope of the tangent line to the curve at the point, and the slope is equal to zero only when the tangent line is horizontal, at the top of a hill or the bottom of a valley, so to speak.

## What is the difference between relative maximum and absolute maximum?

A relative max/min point is a point higher or lower than the points on both of its sides while a global max/min point is a point that is highest or lowest point in the graph. In other words, there can be multiple relative max/min points while there can only be one global/absolute max/min point.

## What is first derivative used for?

The first derivative of a function is an expression which tells us the slope of a tangent line to the curve at any instant. Because of this definition, the first derivative of a function tells us much about the function. If is positive, then must be increasing.

## How do you find the maximum and minimum of a graph?

The y- coordinates (output) at the highest and lowest points are called the absolute maximum and absolute minimum, respectively. To locate absolute maxima and minima from a graph, we need to observe the graph to determine where the graph attains it highest and lowest points on the domain of the function.

## How do you find the relative maximum and minimum of a function?

Find the first derivative of a function f(x) and find the critical numbers. Then, find the second derivative of a function f(x) and put the critical numbers. If the value is negative, the function has relative maxima at that point, if the value is positive, the function has relative maxima at that point.

## What is relative extrema of a function?

5.5. 1 Relative Extrema. ¶ 🔗 A relative maximum point on a function is a point (x,y) on the graph of the function whose y -coordinate is larger than all other y -coordinates on the graph at points “close to” (x,y).

## How many extrema are there?

two

## How do you identify extrema?

Finding Absolute Extrema of f(x) on [a,b]

- Verify that the function is continuous on the interval [a,b] .
- Find all critical points of f(x) that are in the interval [a,b] .
- Evaluate the function at the critical points found in step 1 and the end points.
- Identify the absolute extrema.

## What Extrema means?

Extremum, plural Extrema, in calculus, any point at which the value of a function is largest (a maximum) or smallest (a minimum). There are both absolute and relative (or local) maxima and minima.

## What is a relative function?

Function achieves relative maximum or relative minimum (relative extrema) at points, at which it changes from increasing to decreasing, or vice versa. DEFINITION OF RELATIVE EXTREMA. Let f(x) be a function of x .

## What is the maximum and minimum of a parabola called?

The vertex of a parabola is the highest or lowest point, also known as the maximum or minimum of a parabola.
