[" EXAMPLE "22" Prove that "],[qquad [sin alpha,sin beta,sin gamma],[cos alpha,cos beta,cos gamma],[sin2 alpha,sin2 beta,sin2 gamma]],[=-4sin(alpha-beta)/(2)sin(beta-gamma)/(2)sin(gamma-alpha)/(2)]

Prove that: sin alpha+sin beta+sin gamma-sin(alpha+beta+gamma)=4sin((alpha+beta)/(2))sin((beta+gamma)/(2))sin((gamma+alpha)/(2))

Prove that: sin alpha+sin beta+sin gamma-sin(alpha+beta+gamma)=4sin((alpha+beta)/(2))*sin((beta+gamma)/(2))*sin((gamma+alpha)/(2))

prove that | (sin alpha, sin beta, sin gamma), (cos alpha, cos beta, cos gamma), (sin 2alpha, sin 2beta, sin 2gamma) | = 4sin (1/2) (beta-gamma) * sin (1/2) (gamma-alpha) * sin (1/2) (alpha-beta) xx {sin (beta + gamma) + sin (gamma + alpha) + sin (alpha + beta)}.

Prove the following: "sin" alpha+"sin" beta+"sin" gamma-"sin"(alpha+beta+gamma)=4"sin"(alpha+beta)/(2)"sin"(beta+gamma)/(2)"sin"(gamma+alpha)/(2)

cos alpha+cos beta+cos gamma=0sin alpha+sin beta+sin gamma=0 then the value of sin^(4)alpha+sin^(4)beta+sin^(4)gamma

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

If cos alpha+ cos beta + cos gamma = sin alpha+ sin beta +sin gamma= 0 , then :

If cos alpha+cos beta+cos gamma=0=sin alpha+sin beta+sin gamma then x^(sin(2 alpha-beta-gamma)*x^(sin(2 beta-gamma-alpha)))*x ^(sin(2 gamma-alpha-beta)) is

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
