If `3sin(x y)+4cos(x y)=5` then `dy/dx=`

If 3sin(x y)+4cos(x y)=5,t h e n(dy)/(dx)= (a) -y/x (b) (3sin(x y)+4cos(x y))/(3cos(x y)-4sin(x y)) (c) (3cos(x y)+4sin(x y))/(4cos(x y)-3sin(x y)) (d) (sin^2(a+y))/(sina)

If sin(x y)+cos(x y)=0 , then (dy)/(dx) is

If sin(x y)+cos(x y)=0 , then (dy)/(dx) is

If sin(x y)+cos(x y)=0 , then (dy)/(dx) is

If sin (x+y) +cos (x+y) =1,then (dy)/(dx)=

If sin (x+y) +cos (x+y) =1,then (dy)/(dx)=

If x sin y = 3 sin y + 4 cos y , then (dy)/(dx) =

If cos (xy) =sin (x+y) ,then (dy)/(dx)

If y=sin^(2)x.cos^(3)x, then (dy)/(dx)
