If X_(n)="cos"(pi)/(2^(n))+"isin"(pi)/(2^(n)) , then x_(1), x_(2), x_(3)....oo

If x_(n)=cos(pi/3^(n))+isin((pi)/(3^(n))) , then x_(1),x_(2),x_(3),………………..x_(infty) is equal to

If x_(n)=cos(pi)/(2^(n))+i sin(pi)/(2^(n)), prove that x_(1)x_(2)x_(3)x_(oo)=-1

Statement-I : If x_n=cos(pi//2^n)+isin (pi//2^n) then x_1.x_2.x_3…..=-1 Statement-II : x_n=cos(pi//4^n)+isin(pi//4^n) then x_1.x_2.x_3…..infty=-1

If x_n=cos(pi/(2^n))+isin(pi/(2^n)) , prove that x_1x_2x_3........... x_oo=-1.

If x_n =cos ((pi)/(2^(n)))+isin((pi)/(2^(n))) Prove that x_1 x_2…..x_oo=-1
