This function returns the arc cosine of x, in radians.
acos(x) |
Note: This function is not accessible directly so we need to import math module and then we need to call this function using math static object.
Here is the detail of parameters:
x: Must be a numeric value in the range -1 to 1. If x is greater than 1 then it will generate an error.
The arc cosine of x, in radians.
#!/usr/bin/python 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) |
This will produce following result:
acos(0.64) : 0.876298061168 acos(0) : 1.57079632679 acos(-1) : 3.14159265359 acos(1) : 0.0 |
