C code sin implementaion is slower.

Flat profile:

Each sample counts as 0.01 seconds.

47.88 5.30 5.30 __branred
21.79 7.71 2.41 1 2.41 2.41 main
17.32 9.62 1.92 __sin_fma
5.33 10.21 0.59 malloc
3.44 10.59 0.38 _int_malloc
2.98 10.92 0.33 _int_free
1.18 11.05 0.13 free
0.09 11.06 0.01 sysmalloc
0.00 11.06 0.00 2 0.00 0.00 new_node

I first thought is it due to malloc but after profiling it is due to sin function.
