Evaluate `sin(pi/n)+sin((3pi)/n)+sin((5pi)/n)+........` to n terms.

Find sin( (pi)/n)+sin ((3pi)/n)+sin ((5pi)/n)+…….. to n terms

The value of sin pi/n + sin (3pi)/n+ sin (5pi)/n+... to n terms is equal to

The value of (sin pi)/(n)+(sin(3 pi))/(n)+(sin(5 pi))/(n)+... to n terms is equal to

The value of sinpi/n + sin(3pi)/n + sin(5pi)/n +………. to n terms =

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))

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

Show that sin(pi/n)+sin (3pi/n)+sin (5pi/n)+….n terms=0
