Find the line of intersection of the two planes in vector form :
3x-6y-2z=3 , 2x+y-2z=2

ahahahahaha u cawl this professionalism? :p
explain tou kerain...
-_____- I didn't u did.. :p

1.use english.. -.-
2, it's self-explainatory.... ok, lemme try..
all u do is know that |z-c| = |z-b| makes a bisector b/w points b and c on the argand diagram(hat sketch)... notice, makes sense just like in vectors the magnitude of difference of z and c vectors gives u dist of z frm c and of z-b on rhs gives u dst on z frm b..... so when left pt is less than right it means z is closer to c than b.. so I shaded pts on the side near c (i.e. 0 in that legendary.. ahem.. sketch)....
anyway that's story of blue shade...
for green one.. all u do is go to pt u and make the 2 arguments there... half line of agr=0 and half line of arg = pi/4.. and its supposed to b between them.. shaded that with green....
the common area (shaded insanely) is what we were asked to provide...

now if some1 has trouble understanding.. they better ask their teacher to teach them complex loci properly.. -.-
