for the first one - than you know the graph of sinus or cosinus trigonometric functions so these are periodic signal graph bc. the period of a complet wave than you see is the same with the second and 3rd and 4th and so till infinity 
- an aperiodic signal will be one counter example of above wrote that the second period is different same with first and the 3rd is different same with second and 4th - for example 

hope this is understandably example about what mean an APERIODIC signal
