Given `A=hat(i)+hat(j)+hat(k)andB=-hat(i)-hat(j)-hat(k)` then (A-B) will make angle with A

Evaluate [hat(i) hat(k) hat(j)] + [hat(i) hat(j)hat(k)] .

If vec(A) = hat(i) + hat(j) + hat(k) and B = -hat(i) - hat(j) - hat(k) . Then angle made by (vec(A) - vec(B)) with vec(A) is :

If vec(A) = hat(i) + hat(j) + hat(k) and B = -hat(i) - hat(j) - hat(k) . Then angle made by (vec(A) - vec(B)) with vec(A) is :

If a=hat(i)+2hat(j)-2hat(k), b=2hat(i)-hat(j)+hat(k) and c=hat(i)+3hat(j)-hat(k) , then atimes(btimesc) is equal to

If a=hat(i)+2hat(j)-2hat(k), b=2hat(i)-hat(j)+hat(k) and c=hat(i)+3hat(j)-hat(k) , then atimes(btimesc) is equal to

Find the angle between hat(i)+hat(j)+hat(k) and hat(i)+hat(j)-hat(k) .

Prove that [hat(i)hat(j)hat(k)]=1, and [hat(i)hat(k)hat(j)]=-1 .
