how can we prove the following identity:

sin (
j-1(zn)
n+1
(j +1(²π))
n+1
+ sin(
= 2cos(-
7) sin ( ² (i) (n=)) _
n+1
'n + 1
Transcribed Image Text:sin ( j-1(zn) n+1 (j +1(²π)) n+1 + sin( = 2cos(- 7) sin ( ² (i) (n=)) _ n+1 'n + 1
j 1,2...n-1, z = 1,2,...n
Transcribed Image Text:j 1,2...n-1, z = 1,2,...n
