If `sinx+siny=3(cosy-cosx),` then the value of `(sin3x)/(sin3y)` is

If sin x+siny=3(cosy-cosx), then the value of (sin3x)/(sin3y), is

If sin x+siny=3(cosy-cosx), then the value of (sin3x)/(sin3y), is

If sinx siny = 3 (cosy - cos x) then (sin3x)/(sin3y) =

If sinx - cosx = 0, then the value of (sin^3 x-cos^3 x) is: यदि sinx - cosx = 0 ,तो (sin^3 x-cos^3 x) मान होगा :

If sinx + sin y = sqrt3 (cosy-cos x),"then show that" sin 3x+ sin 3y = 0

If sin x+siny=a, cosx+cosy=b , then what is the value of cos(x-y) ?

If sinx+siny=sqrt(3)(cos y-cos x), then sin3x+sin3y= ___________ (a) 2sin3x (b) 0 (c) 1 (d) none of these

If sinx+siny=p,cosx+cosy=q then sec(x+y)=
