Hi !
im on win7 x64 with AMD CPU, using VS2013 , trying to compile code that uses trigonometry (cos,sin) functions .

while im trying to compile my code with use of those function im experiencing some errors .

compiling as "release" for x86 throws :

error LNK2001: unresolved external symbol __libm_sse2_sin_precise 
error LNK2001: unresolved external symbol __libm_sse2_cos_precise

it doesnt complain while compiling as "debug" version for x86 ,
it also doesnt complain while compiling for x64 .

im using AMD CPU , has it something to do with it ? if so why it works with "debug" version and on x64 ?
(normally i can use trigonometry in plain C executable with use of math.h)

those are my first times with C in relation to Max so im really newbie here . And its really hard to spot things that are causing certain problems by myself .

i need your help guys
