## Introduction to the Critical Points Calculator

The critical point calculator is a valuable online tool designed to help you determine critical points of multivariable functions effortlessly. Whether you're dealing with a single function or multiple variables, this calculator streamlines the process of identifying critical points, which are pivotal in calculus and optimization.

## Understanding Critical Points

Critical points are significant values in a function where its derivative is either zero or undefined. These points play a crucial role in understanding the behavior of a function, especially when it comes to finding extrema (maximum or minimum values) and saddle points.

## Formula Used by Critical Points of Multivariable Functions Calculator

The formula used by the critical point calculator to identify critical points in a function involves the calculation of the derivative(s) and the subsequent analysis of these derivatives. The primary goal is to find the points where the derivative(s) of the function become zero or undefined. These points are potential candidates for critical points.

For a function *f *(*x*) of a single variable, a critical point is typically found where the first derivative *f*′ (*x*) equals zero or is undefined. Mathematically, this can be expressed as:

*f*′ (*x*) = 0 or *f*′ (*x*) is undefined

For a function *f *(*x*,*y*) of two variables, critical points are determined by finding values of *x* and *y* where both partial derivatives ∂f/∂x and ∂f/∂y are either zero or undefined:

- ∂f/∂x= 0 or ∂f/∂x is undefined
- ∂f/∂x = 0 or ∂f/∂y is undefined

For functions with more variables, the process is extended to include an additional partial derivatives calculator with respect to those variables.

The calculator employs these fundamental principles to determine critical points in various types of functions. It evaluates derivatives, examines their values, and identifies points where they meet the criteria of being zero or undefined.
