Is cot x y

Is Cot X Y, Hi , thanks! the question was : did the funtion tan (x) ,cot (x) has a symmetry axis , I tried to look at the function graph and see if there is a symmetry, i think there isn't one but I'm not sure how to get the full picture, and a good explanation why this is true without relying only on the function graph.
