```										Dear     ,DOT PRODUCT of 2 vectors.1.)It gives a sclar.2.)Magnitude of dot product is equal to product of magnitude of two vectors and the cosine of angle between them.Example:- Let A and B be two vectors with angle between them equal to θ.A.B=(magnitude of A)(Magnitude of B)(cosθ)

```										Cross Product:-1.)Vector product of 2 vectors gives a vector.2.)The resultant product vector of 2 vectors is in the direction perpendicular to the plane in which the given vectors are present.3.)Magnitude of cross product of  2 vector is the product of magnitude of 2 vectors and the sine of angle between them.Example:-If A and  B are two vectors, A = a1 i + a2 j + a3 kB = b1 i + b2 j + b3 kmagnitude of A*B=(magnitude of A)(Magnitude of B)(sin θ)A*B=| i        j      k || a1     a2    a3 || b1    b2    b3|i,j,k are components of A and B along x,y,z axesApprove if my answer helped you
