If a, b and c are three coplanar vectors. If a is not parallel to b, show that c=(|[c*a, a*b], [c*b, b*b]|a+|[a*a, c*a], [a*b, c*b]|b)/(|[a*a, a*b], [a*b, b*b]|) .
If the vectors a, b and c are coplanar, then |{:(a, b, c),(a*a, a*b,a*c),(b*a,b*b,b*c):}| is equal to
If a,b and c are in GP,then (b-a)/(b-c)+(b+a)/(b+c)=
the symmetric difference of A and B is not equal to (A-B)nn(B-A)(A-B)uu(B-A)(A uu B)-(A nn B){(A uu B)-A}uu{A nn B}
If A = (a + b , a-b) and B (-a + b, -a-b), then find the distance AB .
For all set A and B, (A uu B) - B = A - B .
If (a+b). (a-b) = 8 and |a| = 8 |b|, then the values of |a| and |b| are
If A = [ (a , b) , (-b , a)] and B = [ (a , b),(b , a)] , find AB .
