Python ACOs () function

Describe

ACOs () returns the inverse cosine radian value of x.

Grammar

The following is the syntax for the ACOs () method:

Import Mathmath.acos (x)

Note:ACOs () is not directly accessible, you need to import the math module, and then call the method through the math static object.

Parameters

• X---values from 1 to 1. If x is greater than 1, an error is generated.

return value

Returns the inverse cosine radian value of x.

Instance

The following shows an example of using the ACOs () method:

#!/usr/bin/python3import Mathprint ("ACOs (0.64):",  Math.acos (0.64)) print ("ACOs (0):",  math.acos (0)) print ( "ACOs ( -1):",  Math.acos ( -1)) print ("ACOs (1):",  Math.acos (1))

When the above instance is run, the output is:

ACOs (0.64):  0.8762980611683406acos (0):  1.5707963267948966acos ( -1):  3.141592653589793acos (1):  0.0
