problem with plotting y=tan(x)

Καλημέρα!
I 'm trying to draw the curve y=tan(x).
- When I draw the curve at the domain (-π/2,π/2) everything is OK (see the 1st code and the image).
- When I draw the curve at other domains (e.g.
(π/2,3π/2)) something goes bad (see the 2nd code and the image.
What is happening? How can I fix it?
