square root
Square root : How to use it?
The sqrt function allows to calculate the square root of a number in exact form.
Syntax :
sqrt(x), x is a number.
Examples :
sqrt(`4`), returns 2
Derivative square root :
To differentiate function square root online, it is possible to use the derivative calculator which allows the calculation of the derivative of the square root function
The derivative of sqrt(x) is derivative(`sqrt(x)`)=`1/(2*sqrt(x))`
Antiderivative square root :
Antiderivative calculator allows to calculate an antiderivative of square root function.
An antiderivative of sqrt(x) is antiderivative(`sqrt(x)`)=`2/3*(x)^(3/2)`
Limit square root :
The limit calculator allows the calculation of limits of the square root function.
The limit of sqrt(x) is limit(`sqrt(x)`)
Graphic square root :The graphing calculator is able to plot square root function in its definition interval.
Square root function
By definition, the square root of a real number x, is a number which squared is equal to x.
- Calculation of the square root
- Derivative of square root
- Antiderivative of square root
- Limit of square root
- The square root function has a limit in `+oo` which is `+oo`.
The square root calculator allows through the sqrt function to calculate online the square root.
For example, to calculate the square root of 9 which notes `sqrt(9)`, enter sqrt(`9`), after calculating the result 3 is returned.
For example, to calculate the square root of 99 which notes `sqrt(9)` enter sqrt(`99`), after calculating the result `3*sqrt(11)` is returned.
Note that the result of the square root calculation is returned in its exact form.
The derivative of the square root is equal to `1/(2*sqrt(x))`.
The antiderivative of the square root is equal to `2/3*(x)^(3/2)=2/3*(sqrt(x))^3`.
-
The limit of the square root exist at `+oo` (plus infinity):
- `lim_(x->+oo)sqrt(x)=+oo`
