## Introduction to Local Extrema Calculator

Saddle Point Calculator is an online tool designed to evaluate the critical and extreme points of functions. It provides maxima and minima points of a given function while performing each step of calculations.

To get the solution to mathematical problems related to extreme points we introduce a multivariable tool that helps you to find extreme points of a function. Whether you're a student studying calculus or a professional tackling complex mathematical problems, our Calculator provides a convenient way to identify critical points and understand the behavior of functions within a given interval.

So, our calculator help you find the local extrema of a function quickly and accurately. Further, if you would like to find the curl of vector field functions in two or maybe three dimensions, you can use our curl vector calculator. Our calculator also help to computes the vector function that is rotating about a specific point in one direction in a few seconds.

## What is the Extrema Points Value?

An extrema point is a function that gives the largest or smallest values with a particular interval to draw a curve of the function.

In mathematics, the extrema point function uses a derivative process to get information about the rate of change of a curve.

The extrema points, also known as extreme points or critical points, are the values of a function where it reaches its maximum (maximum extrema) or minimum (minimum extrema). These points are crucial in mathematical analysis and optimization problems.

Additionally, if you would like to find the divergence of function in a vector field and provides a solution in the scalar function, you can go through our divergence theorem calculator. Our calculator also help to evaluates the vector field whose flux magnitude is in a directionless system in a fraction of a second.

## Evaluation Method of Extreme Points Calculator :

Our calculator works on the basics of the extrema point function. The saddle point calculator is a versatile tool as it can handle all types of complex algebraic functions to find critical points, extrema, absolute minima, and maxima.

When You enter your function in the relative extrema calculator, it checks the nature of the function for derivation. After recognizing the function, it differentiates the function two times to apply the second derivative test. In the second derivative test, keep the function f``(x) equal to zero to get inflection critical points.

At last, it puts critical points on the previous equation f(x) and you will get local maxima and minima values. Let us see an example to know the evaluation process of our extreme points calculator.

Additionally, for computations involving vector fields and gradients, consider using our gradient of a line calculator. Our calculator provides solutions for computing gradients, directional derivatives, and other vector-related operations, facilitating analysis in multivariable calculus and vector calculus.

## Solved Example of Extreme Points

The extreme point can be calculated by using the extreme value calculator but it has to be done manually to know each step. So, an example is given to let you know about that.

### Example:

Consider the following function and find its extrema.

$$ f(x) \;=\; 2x^3 - 3x^2 - 12x + 6 $$

**Solution:**

Calculate f’(x):

$$ f’(x) \;=\; 6x^2 - 6x -12 $$

Set f’(x) = 0 and solve for x:

$$ 6x^2 - 6x - 12 \;=\; 0 $$

This quadratic equation contain two critical points:

$$ x \;=\; -1 \;and\; x \;=\; 2 $$

Analyze f’’(x) = 12x - 6:

As:

$$ x = -1: f”(-1) \;=\; 12 . (-1) - 6 \;=\; -18 , is\; negative $$

So, x = -1 is a local maximum.

And,

$$ x \;=\; 2: f”(2) . 2 - 6 = 18, is\; positive $$

So, x = 2 is a local minimum.
