Question

Define dot and cross product of vectors. Give two examples of each​

Answer 1

Answer:

Dot product and cross product are two types of vector product. The dot product is always used to calculate the angle between two vectors

Answer 2

Dot product is a.k.a. Scalar Product. The final result of Dot product comes out to have only Magnitude and hence is Scalar.

eg: (2i + 3j) • (4i -1j) = 5

(7i - 2j) • (5i + 10j) = 15

Cross Product is a.k.a. Vector Product. The final result of Cross Product has both magnitude and direction hence it is Vector.
