43 :00 d option two vector ka liya possible ha to ksyse orthogonal bol diya why {u,v,w} orthogonal Orthogonal nhi hoga na question me given ha ki (u,w) =-1 this is not equal to zero kayse (u,v,w) orthogonal aa raha hai
At 19.59, W2= {(1,1,0),(0,1,-1)} how (0,1,-1) is zero subspace of x-y+z=0 . I think it is not satisfied because 0-(1)+(-1) is not equal to zero. Any one help I'm right or wrong
