`xy+y^(2)=tanx+y`

Find (dy)/(dx) in the following: (a) x^(3)+x^(2)y+xy^(2)+y^(3)=81(b)xy+y^(2)=tan x+y(c)x^(2)+xy+y^(2)=100

Find dy/dx , if 3xy + y^2 = tanx +2y

If x y+y^2 = tanx+y ,then find (dy)/(dx)

If x y+y^2 = tanx+y ,then find (dy)/(dx)

Find dy/dx if x+y^2=tanx+y

Find dy/dx if x+y^2=tanx+y

Find dy/dx if x+y^2=tanx+y

If x:y::5:2, then (x ^(2) - xy + y ^(2))/( x ^(2) + xy + y ^(2)) = ?

The product of the rational expressions (x^2 - y^2)/(x^2 + 2xy + y^2) and (xy + y^2)/(x^2 - xy) is:

If xy = 6 and x ^(2) y + xy ^(2) + x + y = 63, then the value of x ^(2) + y ^(2) is
