Dear nithin


Representation of power of trignometric ratio in terms trignometric ratio of multiple angel is known as trignometric expansions


 


for example.


cos6q = 1/32{cos 6q+6cos 4q+15cos 2q+10 }


or


cos7q = 1/64{cos 7q+7cos 5q+21cos 3q+35cos q  }


 


these expantion can bederived by puting cosx =(eix+e-ix)/2


  and expand it with the hepl of binomial .
