What is an Inner Product?

An inner product is a mathematical scalar value of the multiplication of two or more vectors of an undetermined size. It is calculated by multiplying the magnitudes of the vectors by the cosine of the angle between them.

Example Calculation

Let's assume the following values:

Step 1: Calculate the inner product:

\[ a \cdot b = 5 \cdot 3 \cdot \cos(60^\circ) = 5 \cdot 3 \cdot 0.5 = 7.5 \]

Therefore, the inner product of the vectors is 7.5.
