If , then the greatest value of is
in L.H.S. we take ‘c’ as constant and take the maximum and minimum value and introduce the inequality.
and equality holds when
Which is always les then .
equality holds when
equality holds when (i) and (ii) both hold,
The value of is where xo denotes the degrees :
