[sigma(2)],[1+sin theta+sin^(2)theta+sin^(3)theta+......oo=4+2sqrt(3),0

If 1+sin theta+sin^(2)theta+sin^(3)theta+...rarr oo=4+2sqrt(3)0

If 1 + sintheta + sin^2theta + sin^3theta +.. oo = 4 + 2sqrt3, 0 lt theta lt pi, theta != pi/2 then

sin theta +sin 2theta+sin3theta+sin4theta=0

If 1+sin theta + sin^(2) theta + ...oo= 4+2sqrt(3), 0 lt theta lt pi and theta != pi/2 , then theta

If 1+sintheta+sin^2theta+sin^3theta+..to oo=4+2sqrt3 0< theta < pi , theta!=pi/2 then

The value of the integral int (sin theta.sin2theta(sin^(6)theta+sin^(4)theta+sin^(2)theta) sqrt(2sin^(4) theta+3sin^(2)theta+6))/(1-cos2theta)d theta is : (where c is a constant of integration)

Prove that sin^(2)theta+sin^(2)2 theta+sin^(2)3 theta+....+sin^(2)n theta=(n)/(2)-(sin n theta cos(n+1)theta)/(2sin theta)
