Question

write expressions for the scaler product of two vectors explaining meaning of their symbols used​

Answer 1

Answer:

The scalar product and vector product are the two methods of multiplying vectors that are most commonly used in physics and astronomy.

Explanation:

• The scalar product of two vectors may be calculated by multiplying the component of one vector in the direction of the other by the magnitude of the other vector.
• The scalar product of a and b is as follows: a b = |a||b| cos This formula may be remembered as "the modulus of the first vector multiplied by the modulus of the second vector multiplied by the cosine of the angle between them." Clearly, b a = |b||a| cos, and hence a b = b a.
