A and B are:-

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}

Find the distance between the points A (a+b,a-b) and B (a-b,-a-b)

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*b=b/(b+a) and for some values of a and b , a*b=4 , then b*a=?
