The log function calculates the logarithm of a number online.
The logarithm function is defined for any number belonging to the interval ]0,`+oo`[,
it notes log.
The logarithm calculator allows calculation of this type of logarithm online.
- Calculation of the logarithm
For the calculation of logarithm of a number, just enter the number and apply
the function log. Thus, for calculating
logarithm of the number 1, you must enter
directly 1, if the button log already appears, the result 0 is returned.
- Derivative of logarithm
The derivative of the logarithm is equal to `1/(x*ln(10))`.
- Antiderivative of logarithm
The antiderivative of the logarithm is equal to `(x*ln(x)-x)/ln(10)`.
- Limits of logarithm
The limits of the logarithm exist at `0` and `+oo`:
- The logarithm function has a limit in `0` which is `-oo`.
- The logarithm function has a limit in `+oo` which is `+oo`.
log(x), x is a number.
log(1), returns 0
Derivative logarithm :
To differentiate function logarithm online,
it is possible to use the derivative calculator which allows the calculation of the derivative of the logarithm function
The derivative of log(x) is derivative(`log(x)`)=`1/(ln(10)*x)`
Antiderivative logarithm :
Antiderivative calculator allows to calculate an antiderivative of logarithm function.
An antiderivative of log(x) is antiderivative(`log(x)`)=`(x*log(x)-x)/ln(10)`
Limit logarithm :
The limit calculator allows the calculation of limits of the logarithm function.
The limit of log(x) is limit(`log(x)`)
Graphic logarithm :
The graphing calculator is able to plot logarithm function in its definition interval.
