दिखाइए की : ` 4sin alpha .sin (alpha +(pi)/( 3)) sin ( alpha +( 2pi)/( 3) ) = sin 3alpha `

Show that 4 sin alpha.sin (alpha + pi/3) sin (alpha + 2pi/3) = sin 3alpha

prove that 4sin alpha*sin(alpha+(pi)/(3))*sin(alpha+(2 pi)/(3))=sin3 alpha

Show that 4sin alpha*sin(alpha+(pi)/(3))sin(alpha+2(pi)/(3))=sin3 alpha

sin alpha+sin(alpha+((2pi)/3))+sin(alpha+((4pi)/3))=0

prove sin alpha+sin(alpha+(2pi)/3)+sin (alpha+(4pi)/3)=0

Prove that sinalpha+sin(alpha+(2pi)/3)+sin(alpha+(4pi)/3)=0 .

Prove the following : sin alpha+ sin (alpha+ (2 pi)/3)+ sin (alpha+ (4 pi)/3)=0 .

sin3 alpha=4sin alpha sin(x+alpha)sin(x-alpha)

The expression (1 + sin 2 alpha )/( cos (2 alpha - 2pi) tan (alpha - (3pi)/(4 ))) -1/4 sin 2 alpha [ cot "" (alpha )/(2) + (alpha )/(2))] when simplified reduces to

Prove that sin alpha+sin(alpha+2pi/3)+sin(alpha+4pi/3)=0
