take the arccosine of a number in python

To take the arccosine of a number in python, you can use the acos method from the math module. Keep in mind that the argument of acos should be between -1 and 1 in order to return a valid result.

Here's an example:

main.py
import math

x = 0.5
result = math.acos(x)

print(result) # prints 1.0471975511965979, which is equivalent to 60 degrees in radians

In this example, we first import the math module to access its functions. Then, we define a variable x to hold our input value, which is 0.5. We then call the acos method on x and assign the result to a variable result. Finally, we print the value of result, which is 1.0471975511965979. This value represents the angle (in radians) whose cosine is 0.5.
