math.sin incorrect result

by default angle in Python is calculated in radians. So, you can try to multiply the angle ( degrees ) by 0.01745 - to convert it to degrees and input the values. print(math.sin(60*0.01745)) 0.8659266112878228

>>> import math
>>> print math.sin.__doc__
sin(x)

Return the sine of x (measured in radians).

math.sin expects its argument to be in radians, not degrees, so:

>>> import math
>>> print math.sin(math.radians(68))
