can u explain vectors
those quantities which requires magnitude and direction both for their representation and obeys parallelogram law of vector addition are called vectors.these are tensors of rank 1.
vectors:
A Quantity having both magnitude and direction and obeys laws of vector addition is called a vector.
Examples:Displacement,Velocity,Acceleration etc.,
Product of vectors:1)cross product 2)Dot product
Cross product:
The vector product of any two vectors is also a vector.
properties of cross product:1)Cross product does not obey commutative law.
2)Cross product obeys distributive law.
Vector is a physical quantity which has both magnitude and direction and obeys law of vector addition and follows the laws of vector radiation.
Example:acceleration,force velacity,pressure
The vector triple product is defined as the cross product of one vector with one cross product of other two.
If A, B and C are three vectors then its vector triple product is given by
A × (B × C) = (A × B) × C = (A · C) B – (A · B) C
