If `cosalpha + cosbeta+ cosgamma = 0 sinalpha + sinbeta+ sin gamma = 0` then the value of `sin^4 alpha + sin^4 beta + sin^4 gamma`

If cosalpha+2cosbeta+3cosgamma=sinalpha+2sinbeta+3singamma=0 then the value of sin 3alpha+8sin3beta+27sin 3gamma , is

If cosalpha+2cosbeta+3cosgamma=sinalpha+2sinbeta+3singamma=0 , then the value of sin3alpha+8sin3beta+27sin3gamma is sin(a+b+gamma) b. 3sin(alpha+beta+gamma) c. 18"sin"(alpha+beta+gamma) d. sin(alpha+2beta+3)

If cosalpha+2cosbeta+3cosgamma=sinalpha+2sinbeta+3singamma=0 , then the value of sin3alpha+8sin3beta+27sin3gamma is sin(a+b+gamma) b. 3sin(alpha+beta+gamma) c. 18"sin"(alpha+beta+gamma) d. sin(alpha+2beta+3)

If cosalpha+cosbeta+cosgamma=sinalpha+sinbeta+singamma=0 , then the value of cos3alpha+cos3beta+cos3gamma is

If cos alpha+cosbeta+cosgamma = 0 = sinalpha + sinbeta + singamma then sin^2alpha+sin^2beta+sin^2gamma=

If cosalpha+2cosbeta+3cosgamma=sinalpha+2sinbeta+3singamma=0 , then the value of sin3alpha+8sin3beta+27sin3gamma is a. sin(alpha+beta+gamma) b. 3sin(alpha+beta+gamma) c. 18"sin"(alpha+beta+gamma) d. sin(alpha+2beta+3)

If cosalpha+cosbeta+cosgamma=0=sinalpha+sinbeta+singamma then sin3alpha+sin3beta+sin3gamma=
