Exponential : How to use it?
The function exp calculates online the exponential of a number.
Syntax :
exp(x), where x is a number.
Examples :
- exp(0)`=1`
- exp(i*pi/3)`=1/2+i*sqrt(3)/2`
- exp(i*x)`=cos(x)+i*sin(x)`
Derivative exponential :
To differentiate function exponential online, it is possible to use the derivative calculator which allows the calculation of the derivative of the exponential function
The derivative of exp(x) is derivative(`exp(x)`)=`exp(x)`
Antiderivative exponential :
Antiderivative calculator allows to calculate an antiderivative of exponential function.
An antiderivative of exp(x) is antiderivative(`exp(x)`)=`exp(x)`
Limit exponential :
The limit calculator allows the calculation of limits of the exponential function.
The limit of exp(x) is limit(`exp(x)`)
Inverse function exponential :
The inverse function of exponential is the napierian logarithm function noted ln.
Graphic exponential :The graphing calculator is able to plot exponential function in its definition interval.
Exponential function
The exponential function is defined for any number belonging to the interval ]`-oo`,`+oo`[, it note exp.
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`.
- `lim_(x->-oo)exp(x)=0`
- `lim_(x->+oo)exp(x)=+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.
