Part Number: MSP430F249

Tool/software: Code Composer Studio

Trigonometric functions are not working , means while compiling it , doesn't shows any errors , but it doesn't executes the any of the following functions.

output = sin(deg2rad(30));
output = sin(deg2rad(45));
output = sin(deg2rad(60));
output = sin(deg2rad(75));
output = sin(deg2rad(90));

Hello Mannem,
did you tried to debug?
Which CCS, TI compiler, math lib do you use?

It is not CCS issue.
It is better to post this sort of things on the compilers forum.

did you include math.h?

Please include a test case.

How do you know that? Exactly what do you see that leads you to that conclusion?

In cases like this, we can often determine the problem just by looking at the assembly code generated by the compiler. I can create that assembly code if you send in a test case. For the source file that contains the problem statements, please submit a test case as described in the article How to Submit a Compiler Test Case.

Thanks and regards,
