All,
I have:
\startMPpage %figure library name: intersection
%initialize scale
numeric u; 10u=3in;
%ellipses
path A, B;
A:=fullcircle xyscaled (4u,3u);
B:=A shifted (2u,0);
draw A withcolor red;
label.ulft(btex $A$ etex, point 3 of A) withcolor red;
draw B withcolor blue;
label.urt(btex $B$ etex, point 1 of B) withcolor blue;
%bounding box
draw bbox currentpicture enlarged (0.5u,0.5u);
\stopMPpage
I need an easy way of shading these areas:
1. A intersect B
2. A union B
3. A intersect (complement of B)
4. (complement of A) intersect B
Thanks
