Question

Find a unit vector perpendicular to Plane ABC (6i+3j+2k=6)

Answer 1

@hartnn

Answer 2

u mean plane 6x +3y +2z =6 ?

Answer 3

yup

Answer 4

unit vector...like what makes the whole thing 0 ish

Answer 5

it's n = 6i +3j +2z. it's the same as the coefficients in the plane formula

Answer 6

omg for real?

Answer 7

let say, n=Ai +Bj +Ck, and PS(x,y,z) is a vector on the plane, so if they are perpendicular, their dot product =0
So Ax+By+Cy =0 (notice A,B,C from the normal vector

Answer 8

ok thanks
