sage: import numpy
sage: sin(numpy.arange(5))
array([ 0.        ,  0.84147098,  0.90929743,  0.14112001, -0.7568025 ])

With the patches at #5081 and #6506, and 6497-numpy-sin.patch on this ticket, I got one doctest failure:

I am unable to reproduce the error above on 4.1.1, so I am re-instating the positive review. (Also, the error itself seems totally unrelated to this patch.)

Replying to @robertwb:

The above error is not due to the patch. Ticket #6825 contains steps to reproduce the errors.
