Since you included <cmath> instead of <math.h>, cosf is in the std
namespace.

It doesn't work.  I put std::cosf and it says it doesn't recognize
std.

I even put using namespace std;
Same problem...

As well, I tried just including <math.h> and it still says can't find
'cosf'.

Am I missing a define somewhere?

BSD C doesn't have the cosf() function,  you probably will have to  
cos() instead.

However I tried this with MSL recrusive last in the access paths using 
#include <cmath> and std::cosf  and that compiled and linked without any 
errors.

There are two possible C libs you can use:  BSD C or MSL C.  Only MSL C
has std::cosf and neither have ::cosf.  The easiest way to use MSL C is
to start with the Pro 8 stationary.  It sets MSLCarbonPrefix.h as your
prefix file, arranges the paths just so, and links to the correct libs.
