Im meant to sketch these 2 graphs, but i cant seem to know what to do with the part highlighted in blue.

And im think then im meant to draw it for a few periods. But i cant continue because i dont know how to draw the part in blue?

hi gomes! :wink:

for the left-hand graph, just draw a little "x" at the position (0, 1/2) :smile:

it's understood that only the point at the centre of the "x" is actually meant! :wink:

(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 :smile:

but your circles are so wonky, i think you should go for the crosses … they're easier to draw! :wink:
