**Part Number:** TMS320F28069M

**Tool/software:** TI C/C++ Compiler

Hi all!

I have a problem with the #include <IQmathLib.h> library. Currently I'm using a Launchpad F28069M, and the idea is that I need to calculate the sine and cosine for some variables in radians. But the IQmath lybrary is not that easy to understand.

My angles values are expressed as a 2*pi*w, and i have to update w several times during a period of time (w will be between 10 and 10000). (This is in order to apply a FFT in my code)

I hope someone has an example of how to apply the sine and cosine applying the IQmath lib so I can adapt it to my code.

Thanks in advance for the help!
