- Calculation of the exponential
With the **exponential calculator**, the function exp can **calculate** the
**exponential online** of a number.

To **calculate the exponential** of a number, just enter the number and to apply the
function **exp**. Thus, for **calculating** the
**exponential ** of the number 0, you must enter
exp(`0`) or
directly 0, if the button exp already appears, the result 1 is returned.

- Derivative of exponential
The derivative of the exponential is equal to exp(x).

- Calculate chain rule of derivatives with exponential
If u is a differentiable function, the **chain rule of derivatives with the exponential function** and the function u is calculated using the following formula
: `(exp(u(x)))'=u'(x)*exp(u(x))`, the
derivative calculator
can perform this type of calculation as this example shows
calculating the derivative of exp(4x+3).

- Antiderivative of exponential
The antiderivative of the exponential is equal to exp(x).

- Limits of exponential
The limits of the exponential exist at `-oo` and `+oo`:
- The exponential function has a limit in `-oo` which is 0.
- The exponential function has a limit in `+oo` which is `+oo`.

- Equation with exponential
The calculator has a solver that allows him to solve a
equation with exponential .
The calculations for obtaining the results are detailed, so it will be possible to solve equations like
`exp(x)=2`
or like
`exp(2*x+4)=3`
or like
`exp(x^2-1)=1`
with the steps calculations.
