Question

Find the two unit vectors perpendicular to ã' = (1, 3, -2) and 7 = (0,1,2).

Answer 1

let å Ĉ are vectors then cross Product axb is orthogonal to both ä and b desired unit vector, then can be obtained by 1 1 årb ll läroll given as 54, 3,-27 :i+ 35 -22 b=20,1,2)= oir ;+2k Tårn li j k l 1 3 1 11 -2 1 13-21 Il 21 2) tk 11 31 i (342-146-23) - 5 (1x2-(-2)01] + $(291-003) 17(6+2) - 3(2-0) **(1-0): - 8i- aj tk
