Ifa= cis alpha,b=cis beta,c= cis gamma then (a^(3)b^(3))/(c^(2))=

If a=cis alpha , b= cis beta , c= cis gamma and (a)/(b)+(b)/(c)+(c)/(a)=1 then cos (alpha-beta)+cos (beta-gamma)+cos (gamma-alpha)=

If x=cis alpha ,y=cis beta , then find xy+(1)/(xy)

If cis alpha.cis beta.cis gamma=cis x then the value of x is

If x=cis alpha ,y=cis beta , then find x^4y^3+(1)/(x^4y^3)

Ifx=cis alpha,b=cis beta,c=cis gamma and x+y+z=0 then find the value of (1)/(x)+(1)/(y)+(1)/(z)

a=cos alpha+i sin alpha,b=e^(i beta),c=cis theta and (ab)/(c)=, then find the value of (alpha+beta-theta) in [0,pi].

If A+B+C= 180^@ and cis A=x,cis B=y,cis C=z, them xyz=
