hi gomes! 
for the left-hand graph, just draw a little "x" at the position (0, 1/2)
…
it's understood that only the point at the centre of the "x" is actually meant!
(and then repeat for a few periods, as you say)
(oh, i think some people draw a dot with a circle round it instead)

about the size you've done them …
but your circles are so wonky, i think you should go for the crosses … they're easier to draw!
