Have a look at this http://www.it-iss.com/mysql/mysql-triggers/ will explain how triggers work with examples:

Your particular trigger would be something like:

DELIMITER $$
CREATE TRIGGER appointment01
AFTER UPDATE ON appointments
FOR EACH ROW BEGIN
UPDATE patients SET date_of_last_appointment = new.date_of_appointment WHERE patient_id = new.patient_id;
END;
$$
