The ACOs () method returns the inverse cosine value of x, expressed in radians.
Grammar
The following is the syntax for the ACOs () method:
ACOs (x)
Note: This function is not directly accessible, so we need to import the math module and then call this function with the static object of math.
Parameters
- X-This must be a numeric value within the range-1 to 1, and if X is greater than 1, it will produce an error.
return value
This method returns the X-cosine, expressed in radians.
Example
The following example shows the use of the ACOs () method.
#!/usr/bin/pythonimport mathprint "ACOs (0.64):", Math.acos (0.64) print "ACOs (0):", Math.acos (0) print "ACOs ( -1):", Mat H.acos ( -1) print "ACOs (1):", Math.acos (1)
When we run the above program, it produces the following results:
ACOs (0.64): 0.876298061168acos (0): 1.57079632679acos ( -1): 3.14159265359acos (1): 0.0
