Asymptote:A line that the graph of a function approaches but never touches. In the case of sin(1/x), the y-axis serves as an asymptote.
Periodic Function: A function that repeats its values in regular intervals. While sin(1/x) does not have a fixed period, it exhibits periodic behavior as x approaches zero.
Limit:The value that a function approaches as the input (x) gets arbitrarily close to a certain point or infinity. For sin(1/x), the limit as x approaches zero does not exist because it oscillates indefinitely.
