They are in <math.h> or in any file it includes.
FYI, depending on whether you choose to use inline implementations, some
math functions are declared in <bits/mathcalls.h> or defined in
<bits/mathinline.h>. Of course, those files are not intended to be
explicitely included by the programmer since they are not part of the
standard and are {platform,compiler}-dependent.

<tgmath.h> provides type-generic macros for math functions. If you include
that file, in your example, sin(X) where X is of type float/double/long
double/_Complex, the actual function will be called. i.e. sin[fl]/csin[fl]

Please be more specific.
