It is an amazing source that provides solutions for complex or lengthy calculations of a given function in one click only. You just need to give the input value in this saddle point calculator and it will generate a function solution without taking any external assistance.

## What is an Extreme Point?

An extrema function is a procedure that is used in calculus to find the extrema points and **critical points** of a given function. It refers to different conditions for specific functions to determine the critical points.

This process helps to identify the points where a given function reaches its local maximum or minimum values. These extrema points are crucial for solving calculus, engineering, and scientific problems easily.

## How to Calculate Absolute Extrema Point?

The extreme points calculator uses the differentiate method to **calculate the absolute extrema** point. After the derivation of a given function, it uses certain conditions that define the local maxim or minim points of the given function at particular points.

Here is the complete calculation process of the extreme values calculator to let you know the whole process of finding absolute extrema.

**Step 1**:

Identify the given function f(x) and differentiate it with respect to x

**Step 2**:

To find the critical point, the extreme calculator usually takes the result of the first derivative function equal to zero as f′(x)=0 or uses the algebraic method to get a solution in a and b values.

**Step 3**:

Then again differentiate the result of the first derivative with respect to x

**Step 4**:

Apply the condition of the extrema point to find the local maxima or minima value.

$$ f′′(x) > 0\; (local\; minimum) $$

$$ f′′(x) < 0\; (local\; maximum) $$

$$ f′′(x) \;=\; 0\; then\; the\; test\; fail $$

**Step 5**:

Put the critical point value in the given function f(x) one by one

**Step 6**:

Lastly, use the local maxima or minimum point and sketch a graph to get a visual understanding of the given function.

## Practical Example of Extrema Point:

An **example** of an extrema point is given below to let you know how the relative extrema calculator works and solves the problems.

**Example**:

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

**Solution**:

Given function is,

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

Differentiate with respect to x,

$$ f’(x) \;=\; \frac{d}{dx}(x^3 - 3x^2 + 2x) $$

$$ f’(x) \;=\; 3x^2 - 6x + 2 $$

Solve the result of derivation by keeping it equal to zero for the critical point,

$$ 3x^2 - 6x + 2 \;=\; 0 $$

This is a quadratic equation so used its formula to get a solution,

Here, a = 3, b = -6 and c = 2.

$$ x \;=\; \frac{-(-6) \pm \sqrt{(-6)^2 - 4 . 3 . 2}}{2 . 3} $$

$$ x \;=\; \frac{6 \pm \sqrt{36 - 24}}{6} $$

$$ x \;=\; \frac{6 \pm \sqrt{12}}{6} $$

$$ x \;=\; \frac{6 \pm 2\sqrt{3}}{6} $$

$$ x \;=\; 1 \pm \frac{\sqrt{3}}{3} $$

So the critical point is,

$$ x_1 \;=\; 1 + \frac{\sqrt{3}}{3} $$

$$ x_2 \;=\; 1 - \frac{\sqrt{3}}{3} $$

Differentiate the result of first derivative again with respect to x,

$$ f’’(x) \;=\; \frac{d}{dx}(3x^2 - 6x + 2) $$

$$ f’’(x) \;=\; 6x - 6 $$

Apply the condition of the second derivative test to find relative maxima or minima values,

$$ For\; x_1 \;=\; 1 + \frac{\sqrt{3}}{3} $$

$$ f’’ \left(1 + \frac{\sqrt{3}}{3} \right) \;=\; 6 \left( 1 + \frac{\sqrt{3}}{3} \right) - 6 $$

$$ f’’ \left(1 + \frac{\sqrt{3}}{3} \right) \;=\; 6 + 2\sqrt{3} - 6 $$

$$ f’’ \left( 1 + \frac{\sqrt{3}}{3} \right) \;=\; 2\sqrt{3} > 0 $$

x1 is a local minimum.

$$ For\; x_2 \;=\; 1 - \frac{\sqrt{3}}{3} $$

$$ f’’ \left( 1 - \frac{\sqrt{3}}{3} \right) \;=\; 6 \left(1 - \frac{\sqrt{3}}{3} \right) - 6 $$

$$ f’’ \left(1 - \frac{\sqrt{3}}{3} \right) \;=\; 6 - 2\sqrt{3} - 6 $$

$$ f’’ \left(1 - \frac{\sqrt{3}}{3} \right) \;=\; -2\sqrt{3} < 0 $$

x2 is a local maximum.

Finally put the critical point value in the given function f(x),

$$ For\; x_1 \;=\; 1 + \frac{\sqrt{3}}{3} $$

$$ f \left(1 + \frac{\sqrt{3}}{3} \right) \;=\; \left(1 + \frac{\sqrt{3}}{3} \right)^3 - 3 \left(1 + \frac{\sqrt{3}}{3} \right)^2 + 2 \left(1 + \frac{\sqrt{3}}{3} \right) $$

$$ For\; x_2 \;=\; 1 - \frac{\sqrt{3}}{3} $$

$$ f \left(1 + \frac{\sqrt{3}}{3} \right) \;=\; \left(1 + \frac{\sqrt{3}}{3} \right)^3 - 3 \left(1 + \frac{\sqrt{3}}{3} \right)^2 + 2 \left( 1 + \frac{\sqrt{3}}{3} \right) $$

$$ For\; x_2 \;=\; 1 - \frac{\sqrt{3}}{3} $$

$$ f \left(1 - \frac{\sqrt{3}}{3} \right) \;=\; \left(1 - \frac{\sqrt{3}}{3} \right)^3 - 3 \left(1 - \frac{\sqrt{3}}{3} \right)^2 + 2 \left(1 - \frac{\sqrt{3}}{3} \right) $$

And simplify you get the solution of given function is,

$$ f(x_1) \;=\; f \left(1 + \frac{\sqrt{3}}{3} \right) \approx 0.816 $$

$$ f(x_2) \;=\; f \left(1 - \frac{\sqrt{3}}{3} \right) \approx -0.816 $$
