" Eund the sum of the series,"sin x+sin3x+sin5x+......+sin(2k-1)x

Find the sum of sin x+3sin3x+5sin5x+.........+(2k-1)sin(2k-1)x

Find the sum of sinx+3sin3x+5sin5x+...........+(2k-1)sin(2k-1)x.

Find the sum of sinx+3sin3x+5sin5x+...........+(2k-1)sin(2k-1)x.

If s_(n) ,be the sum of n terms of the series,sin x+sin2x+sin3x+......+sin nx then show that Lim it_(n rarr oo)(s_(1)+s_(2)+......+s_(n))/(n)=(1)/(2)cot((x)/(2))(x!=2k pi,k in I)

sin x + sin 3x + sin 5x =0

sin x + sin 3x + sin 5x =0

sin x + sin 3x + sin 5x =0

sin x + sin 3x + sin 5x =0
