What is the formula of triple vector product?
What is the formula of triple vector product?
1 The vector triple product of u, v and w is u × (v × w).
What is the cross product of 3 vectors?
The two nonequivalent triple cross products of three vectors a, b, c. In each case, two vectors define a plane, the other is out of the plane and can be split into parallel and perpendicular components to the cross product of the vectors defining the plane.
How do you do the triple cross product?

- THE TRIPLE CROSS PRODUCT. A × (B × C)
- Note that the vector G = B × C is perpendicular to the plane on which vectors B and. C lie.
- {
- (A · C)B − (A · B)C.
- }
- Selecting arbitrarily A = k, B = j, and C = k, for instance, and substituting in the above equality, one obtains λ = 1.
What is scalar triple product formula?
The scalar triple product of three vectors a, b, and c is (a×b)⋅c. The scalar triple product is important because its absolute value |(a×b)⋅c| is the volume of the parallelepiped spanned by a, b, and c (i.e., the parallelepiped whose adjacent sides are the vectors a, b, and c).
What is AXB XC?
(a x b) x c = (a c)b – (b c)a (1) for the repeated vector cross product. This vector-valued identity is easily seen to be. completely equivalent to the scalar-valued identity.
Is cross product a scalar?
One type, the dot product, is a scalar product; the result of the dot product of two vectors is a scalar. The other type, called the cross product, is a vector product since it yields another vector rather than a scalar.
What is a Bxc?
a x (b x c) = (a x b) x c. For example, if the three vectors are considered as position vectors, with the origin as a common end-point, then a x (b x c) is perpendicular to both a and b x c, the latter of which is already perpendicular to both b and c. It therefore lies in the plane of b and c.
