If 3sin beta=sin(2 alpha+beta) then

Show that :- 4 sin beta sin(60^(@)+beta)sin(60^(@)-beta)=sin 3beta .

2sin^(2)beta+4cos(alpha+beta)sin alpha sin beta+cos2(alpha+beta)=

If 4tan beta=3, then (4sin beta-3cos beta)/(4sin beta+3cos beta)=

If 4 tan beta = 3 , then (4 sin beta - 3 cos beta)/( 4 sin beta + 3 cos beta)=

The maximum value of determinant |{:(cos(alpha+beta),sin alpha,-cos alpha),(-sin(alpha+beta),cos alpha, sin alpha),(cos 2beta,sin beta, cos beta):}| is ___________

What is sin (alpha+beta) - 2 sin alpha cos beta + sin(alpha- beta) =

If x = sin alpha, y = sin beta, z = sin (alpha + beta) then cos (alpha + beta) =

sin alpha + sin beta = a, cos alpha + cos beta = b rArr sin (alpha + beta)
