Question: Consider the equation exy + cos(x + xy) 2 2y = 0, (x, y) = R Does the set of solutions of this equation

Consider the equation exy + cos(x + xy) 2 2y = 0,

Consider the equation exy + cos(x + xy) 2 2y = 0, (x, y) = R Does the set of solutions of this equation in a neighborhood of the solution (0,0) implicitly define one of the components of the point (x, y) as a function of the other component? If so, compute the derivative of this function at the point 0. (Hint: Use the Dini's Theorem.)
