Periodic Signals Revisited

The function chosen (by randomly clicking a name) from hw1 is y=sin(t). Found here: http://cobweb.ecn.purdue.edu/~mboutin/ECE301/Index.html

I chose to modify the signal a bit and make it y = sin(5t).

If you plot the signal in DT sampling at 5Hz you get a non-periodic signal as follows:

It looks very close to periodic, but it does not follow the definition of x(n+N) = x(n) that was learned in class.
