Find the intersection of pi1, pi2, pi3, and describe geometrically in each case.
a) pi1: x-y+2z=7
b) pi1: x+y-z=3
so this is my work:
ok, now I can't find any way that both a) and b) have intersections because n1, n2, n3 are never parallel or have n1=kn2=kn3 .. i think i'm doing something wrong here. please help me out and demonstrate the correct method to this question. thanks in advance!
however there is a part c) and this one worked out (i think?):
so this is my answer: not sure if it correct
pi1//pi2 and no common intersections
