Just add this testcase as well to series/test_series.py:

In [2]: (sin(x**50)/x**51).series(x, n=0)
Out[2]:
1
- + O(1)
x

@sachin-4099 I added the test, however it is causing an assertion error and I can't seem to figure out why. I ran the command on the master and it worked fine, so I was wondering if it could possibly be a syntax issue or something else.

The contents of the test are assert (sin(x**50)/x**51).series(x, n=0) == 1/x + O(1)

[sachin-4099]

This will work:
assert (sin(x**50)/x**51).series(x, n=0) == 1/x + O(1, x)

Looks good to me. This can be merged @jksuom.

Thanks.
