Arccosine

The arccos function allows the calculation of the arc cosine of a number. The arccos function is the inverse functions of the cosine function.


Arccosine function

The arccosine function is the inverse function of the cosine function, it calculates the arc cosine of a number online.

The number on which you wish to apply the fonction arccosine function must belong to the range [-1,1].

  1. Calculation of the arccosine
  2. To calculate the arccosine of a number, just enter the number and apply the arccos function. Thus, for calculating the arccosine of the number following 0.4, you must enter arccos(`0.4`) or directly 0.4, if the arccos button already appears, result 1.15927948073 is returned.

  3. Derivative of arccosine
  4. The derivative of the arccosine is equal to `-1/sqrt(1-(x)^2)`.

  5. Antiderivative of arccosine
  6. The antiderivative of the arccosine is equal to `x*arccos(x)-sqrt(1-(x)^2)`.

  7. Table of remarkable values
  8. arccos(`-1`)`pi`
    arccos(`-sqrt(3)/2`)`5*pi/6`
    arccos(`-sqrt(2)/2`)`3*pi/4`
    arccos(`-1/2`)`2*pi/3`
    arccos(`0`)`pi/2`
    arccos(`1/2`)`pi/3`
    arccos(`sqrt(2)/2`)`pi/4`
    arccos(`sqrt(3)/2`)`pi/6`
    arccos(`1`)`0`

Syntax :

arccos(x) where x is a number.

Other notation sometimes used : acos


Examples :

arccos(`1`) returns 0


Derivative arccosine :

To differentiate function arccosine online, it is possible to use the derivative calculator which allows the calculation of the derivative of the arccosine function

The derivative of arccos(x) is derivative(`"arccos"(x)`)=`-1/sqrt(1-(x)^2)`


Antiderivative arccosine :

Antiderivative calculator allows to calculate an antiderivative of arccosine function.

An antiderivative of arccos(x) is antiderivative(`"arccos"(x)`)=`x*"arccos"(x)-sqrt(1-(x)^2)`


Limit arccosine :

The limit calculator allows the calculation of limits of the arccosine function.

The limit of arccos(x) is limit(`"arccos"(x)`)


Inverse function arccosine :

The inverse function of arccosine is the cosine function noted cos.



Graphic arccosine :

The graphing calculator is able to plot arccosine function in its definition interval.
