# Find a · b.4. a = ⟨6, −2, 3⟩, b = ⟨2, 5, −1⟩

To determine

To find: A dot product between a and b .

Explanation

Given:

a=6,2,3 and b=2,5,1 .

A minimum of two vectors are required to perform a dot product. The resultant dot product of two vectors is scalar. So, the dot product is also known as a scalar product.

Consider a general expression to find the dot product between two three-dimensional vectors.

ab=a1,a2,a3b1,b2,b3=a1b1+a2b2+
