let p = sin(pi + a) + sin(2pi + a) + sin(3pi + a) + sin(4pi + a) + -----------------------+ sin(2kpi + a)
       separate odd and even together,
= [sin(pi +a) + sin(3pi +a) + sin(5pi +a) + -----------+] + [sin(2pi +a) + sin(4pi +a) + sin(6pi +a)+------+ ]
=[ -sina - sina -sina -sina -----] + [ sina + sina +sina sina + ------+]
= 0
