3. Let f(x, y) =e(+1) cos((k+1)y). Consider the surface z = f(x,y). (a) Find the parametric equations of the tangent lines to the traces of this function corresponding to (x,y) = (0,). (10 points) (b) Find the equation of the plane tangent to the surface at the same point. (10 points) 3. Let f(x, y) =e(+1) cos((k+1)y). Consider the surface z = f(x,y).
