I : If cos alpha + cos beta + cos gamma =3 " then " sin alpha + sin beta + sin gamma =0 II : If sin alpha + sin beta + sin gamma =3 " then " cos alpha + cos beta + cos gamma =0

If cos alpha + cos beta + cos gamma = 3 then sin alpha + sin beta + sin gamma =

If cos alpha + cos beta + cos gamma = 0 and also sin alpha + sin beta + sin gamma= 0, then prove that: cos 3 alpha + cos 3beta + cos 3gamma = 3 cos (alpha + beta + gamma)

If sin alpha+sin beta+sin gamma=0=cos alpha+cos beta+cos gamma, then the value of sin^(2)alpha+sin^(2)beta+sin^(2)gamma, is

If sin alpha + sin beta + sin gamma =3, then the value of (cos alpha + cos beta+ cos gamma) is-

If cos alpha+2cos beta+3cos gamma=sin alpha+2sin beta+3sin gamma=0 then the value of sin3 alpha+8sin3 beta+27sin3 gamma is sin(a+b+gamma)b.3sin(alpha+beta+gamma) c.18sin(alpha+beta+gamma) d.sin(alpha+2 beta+3)

If cos alpha + cos beta + cos gamma = 0 = sin alpha + sin beta + sin gamma then show that sin 3 alpha + sin 3 beta + sin 3 gamma = 3 sin ( alpha + beta + gamma)

If cos alpha + cos beta + cos gamma = 0 = sin alpha + sin beta + sin gamma then show that cos 3 alpha + cos 3 beta + cos 3 gamma = 3 cos ( alpha + beta + gamma)
