hey we're trying to use a simple cosine function call in our code, and we've done the "#include <math.h>" already but we keep getting an error of

"Error - could not find definition of symbol 'cos' in file 'C:\Program Files\MPLAB IDE\default\user_routines.o'. "

when we try to compile. obviously, this is using the MPLAB IDE v6.30... has anyone else successfully used the math functions in their code, or any suggestions on how to fix this?

thanks in advance,
jason
