In the sense that they are related by showing something to somebody. There is this difference; viz., Present is like introducing. You have a new daughter-in-law and at the wedding reception her mother is introduced. "Please let me Present Barbars' mother, Marion Smith." Represent is like authenticating something that is being introduced. You have just bought a new car and dropped by the barbershop. "Say, did I tell you that I bought a new convertible. Man! It represents the new small style for convertibles."
