## Online Derivative Calculator

This tool calculates the derivative of a function online. Common functions are accepted: sine, cosine, tangent, logarithm (log), exponential, square root, etc. (See table below).

## Importance and Usage of Derivatives in Mathematics

The derivative of a function is a fundamental concept in mathematics, crucial in various fields such as engineering, physics, economics, and even in biological sciences. It allows us to measure how one quantity changes in response to a change in another quantity. In practice, this means understanding the rate of change, like the speed of a moving object or the growth rate of a population.

This online derivative calculator is designed to simplify and speed up the derivation process, making mathematical analysis more accessible and understandable, whether for students, teachers, or professionals. With this tool, it is possible to quickly obtain the derivatives of complex functions, thus facilitating the study and application of mathematical concepts in real life.

## How to Use the Calculator

The procedure to use this calculator is simple and intuitive. Here are the steps to follow:

• Enter the main variable (e.g., x).
• Input the function to be derived (e.g., x^2+x+1).

## Usage Example

Here are some examples to illustrate how to use the calculator:

• To calculate the derivative of f(x) = x^2, enter x as the variable, x^2 as the function.
• To calculate the derivative of the function f(x) = sin(x), enter x, sin(x) respectively.

## Data Entry Guide

Variables A function can have one or more variables, but only one main variable. A variable is a single lowercase or uppercase letter. Examples: A function f with one main variable : f(x) = 4*x A function g with one main variable x and a secondary parameter m, g(x) = 4*x*m + x + 1,In this case, enter x in the “main variable” field Use a dot as decimal separator + (addition), - (substration), * (multiplication), / (division), ^ (power), For multiply operator, enter a*b not a.b nor ab. Example: 2*x. You may use these constants : pi (approx. 3.14), e (approx. 2,72) Examples: f(x) = pi * x or f(x) = e * (x+1+2*e)2 You may use theses functions in the expression of f(x) sqrt(x) (square root), exp(x) (exponential function), log(x) or ln (natural logarithm), You may use theses functions in the expression of f(x) sin (sine), cos (cosine), tan (tangent), cot (cotangent), sec (secant), csc (cosecant), You may use theses functions in the expression of f(x) arcsin (arcsine), arccos (arccosine), arctan (arctangent), arccot (arcotangent), arcsec (arcsecant), arccsc (arccosecant), You may use theses functions in the expression of f(x) sinh (hyperbolic sine), cosh (hyperbolic cosine), tanh (hyperbolic tangent), coth (hyperbolic cotangent), sech (hyperbolic secante), csch (hyperbolic cosecant) You may use theses functions in the expression of f(x) asinh (inverse hyperbolic sine), acosh (inverse hyperbolic cosine), atanh (inverse hyperbolic tangent), acoth (inverse hyperbolic cotangent), asech (inverse hyperbolic secant), acsch (inverse hyperbolic cosecant)
