the second one shade A without the intersection area and the first one will be all the diagram except B

BUT ITS WRITTEN A ^ THIS MEANS A SHOULD NOT BE THERE

 

[zaid1q]

------------------------
we need only ONE POINT ON X which make a difference of 0.5 in Y
if we suggested .7 and .2 , they will not match on one point on X ...... SO we should find that one point and can't be any other1.....got it???

ohh thank uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

first diagram

[always-smile :)]

In 2nd Diagram shade All but The intersection...and Gap in the Middle will not be shaded!
