The acos() function returns the arccosine of a number as a numeric value value between 0 and PI radians.
|x||Required. Must be a numeric value in the range -1 to 1|
Note: If the parameter x is outside the range -1 to 1, the browser will return -1.#IND.
Note: -1 will return the value of PI.
In this example we will get the arccosine of different numbers:
The output of the code above will be:
