In Exercises 15-42, translate each argument into symbolic form. Then determine whether the argument is valid or invalid. You may use a truth table or, if applicable, compare the argument’s symbolic form to a standard valid or invalid form. (You can ignore differences in past, present, and future tense.) If I’m at the beach, then I swim in the ocean. If I swim in the ocean, I swim I feel refreshed . ∴ If I'm not at the beach, then I don't feel refreshed .
