I am using LPCXpresso IDE for programming LPC1769, as core library CMSISv2p00_LPC17xx is being used. And I Have chosen REDLIB None by default.

problem that I am encountering, is that, Trigonometric functions are not working, I have included math.h too, its not showing any errors or warning, using of functions like sin, cos, tan and etc returns zero value always.

Any suggestion and help regards to this will be highly appreciated!

Please upgrade your version of LPCXpresso to v7.4.0 - there were some bugs in the trigonometric functions that have been fixed since the version that you are using.
