the angle between vector A and vector B is theta..calculate value of triple product of(all are vectors) ------>A.(B X A)
Asked by Rohan Astik | 2nd Oct, 2013, 09:27: PM
The dot product (also known as the scalar product) of two vectors is defined to be
A B = AB cos ?
where ? is the angle that A and B form when placed tail-to-tail.
Since it is a scalar, the product is commutative
A B = B A
Geometrically, A B = ABA where BA is the projection of B on A , as shown in Fig.
It is also equal to BAB , where AB is the projection of A on B .
The combination (A × B) · C is known as the triple scalar product. A × B is a vector.
The dot product of this vector with the vector C gives a scalar.
