Ok, I think I am missing something - I am a bit lost in the Cython jargon.
Here is where I stand, let me know where I am going wrong... I compiled
with cython.py -a test.py, but it isn't working. If I am completely not on
the right track, feel free to let me know :)

##### test.py (Pure python file) #####
from math import sin
def f(r):
s=sin(r)
return s
r=3.141592654/3.0
print f(r)
#### test.pxd #####
cimport cython
import cython
cimport math_override
@cython.locals(s=cython.
double)
cpdef f(double r)
#### math_override.pxd #####
cdef extern from "math.h":
double sin_d "sin" (double x)
float sin_f "sin" (float x)
cpdef inline double sin(double x):
return sin_d(x)
cpdef inline float sin(float x):
return sin_f(x)
