Python3 acos () function
description
acos () returns the inverse cosine of x radians.
grammar
The following is the syntax acos () method:
import math math.acos(x)
Note: acos () is not directly accessible, you need to import math module, and then call the method by math static objects.
parameter
- x - values between -1 and 1. If x is greater than 1, it will generate an error.
return value
Returns the arc cosine of x in radians.
Examples
The following illustrates the use of acos () method Example:
#!/usr/bin/python3
import math
print ("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))
After running the above example output is:
acos(0.64) : 0.8762980611683406 acos(0) : 1.5707963267948966 acos(-1) : 3.141592653589793 acos(1) : 0.0
