Answer by longjonsilver(2297) (Show Source): You can put this solution on YOUR website!
A circle general equation is given by where centre is (a,b) and radius = r.

So, for second quadrant, you want a centre having negative x and positive y, lets pick (-4,4) and a radius of 1...keep it simple :-)

So, we get -->

As for semi-circle, choose your bounds for printing on the graph as x between -3 and -4, so it misses out the other half (-4 to -5).

Ok?
