" If "sin y=x sin(a+y)," then "dy/dx" is "

If y^y=x sin y , then dy/dx =

If sin y = x sin (alpha + y) then (dy)/(dx) =

y=x^(x sin x) then (dy)/(dx)

If y^y=x sin y , then (dy)/(dx) =

if y+x=sin(y+x) then (dy)/(dx)

If sin y = x sin(a+y), then show that dy/dx = frac{ sin^2 (a+y)}{sin a}

If sin y= x sin (a+ y) and (dy)/(dx)= (A )/(1 + x^(2)-2x cos a) then the value of A is …… [a] 2 [b] CosA [c] SinA [d] 1/2
