why you think to use this fact : u\cdot v= |u||v|cos(\theta) and |u\times v|= |u||v| sin(\theta) in your arguments? I CAN'T SEE IT!
this is my new argument ::
yes v = w.
u.v = v.u and u x v = u x w implies that u.(v-w)=0 and u x (v-w) = 0 implies that u perpendicular with (v-w) and u parallel...
Homework Statement
describe the set of points in space whose coordinate satisfy the given equation or pair of equations:
(i) z=2y (ii) 3x=4y, z=1
if (i) or (ii) represents a line in space, give a unit vector that is parallel to the line. If (i) or (ii) represents a plane, give a unit...
Homework Statement
let u be a nonzero vector in space and let v and w be any two vectors in space. if u.v = u.w and u x v = u x w, can you conclude that v=w? give reason for your answer.
