x^(2)quad " A."quad xy+y^(2)=tan x+y

xy = tan (x + 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 xy^2 + y^2 = tan x + y

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

Find (dy)/(dx) in the following xy + y^(2)= tan x + y

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

If x^(2) + y^(2) -3xy = 0 and x gt y then find the value of log_(xy)(x-y) .

Find (dy)/(dx) in the following: xy+y^(2)=tan x+y

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