If siny=x sin(a+y) , prove that, (dy)/(dx)=(sin a)/(1-2x cos a +x^(2)) .

If sin y=x sin(a+y), then show that: (dy)/(dx)=(sin a)/(1-2x cos a+x^(2))

If sin y = x sin (a + y) prove that (dy) / (dx) = (sin a) / (1-2x cos a + x ^ (2))

If y,=x sin y, prove that (dy)/(dx),=(sin y)/((1-x cos y))

If sin y=x sin(y+a) and (dy)/(dx)=(A)/(1+x^(2)-2x cos a) then the value of A is

If sin y=x sin(y+a) and (dy)/(dx)=(A)/(1+x^(2)-2x cos a) ,then the value of A if x=0 and y=0 is (A) 2 (B) cos a (C) sin a (D) sin2a

Solve (dy)/(dx)=(sin y+x)/(sin2y-x cos y)

if y+cos y=sin x , (dy)/(dx)=

If y = x sin y prove that (dy) / (dx) = (sin y) / ((1-x cos y))

If sin y = x sin (y - a) and (dy)/(dx) = A/(1 + x^2 - 2x cos a) then the value of A is
