sin  + cos
= 2 [sin / 2+ cos/ 2]
= 2sin( +  /4]
This is the most common simplification ... though many more are possible

Dear abhinavasoundar,
we are not getting what exactly you want to ask .
as elessar_iitkgp and ruhi has given you the two different forms in which you can transform the (sin+cos). so please post the complete question.
