Assertion A: `sin(pi/n)+sin(3pi)/n+sin(5pi)/n+.....` to n terms=0 Reason R: `sinalpha+sin(alpha+beta)+.......` to n terms=`sin(nbeta/2)/sin(beta/2).sin((2alpha+(n-1)beta)/2)`

Assertion (A) : "sin" (pi)/(n)+"sin" (3pi)/(n)+"sin"(5pi)/(n)+....+ to n terms=0 Reason (R) : sin alpha+ sin (alpha+ beta)+...+ to n terms =(Sin ((n beta)/(2)))/(Sin beta//2)xxsin ((2 alpha+(n-1)beta)/(2))
