math.sin incorrect result

Question

>>> import math
>>> math.sin(68)
-0.897927680689

sin(68)=0.927(3dp)

Any ideas about why I am getting this result? Thanks.

Answer 1

>>> 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))
0.927183854567
