[Solved] Wrong cosine? Why?

GiovaBici

Hello everybody. I would need to calculate the cosine of an angle. I used the math.cos () function, but the result I am getting is wrong. can anyone tell me why? thank you.
I am attaching the text:

import math
print(math.cos(60))

in the console, as a result, is:

-0.9524129804151563

Otherwise, can you tell me another method with which to calculate the cosine?
Thank you

RTFM... https://docs.python.org/3/library/math.html#math.cos Return the cosine of x radians.

@ccc said:

returns its results in radians

The angle has to be given in radians but cos returns a number between -1 and +1
