Description: WebThey can be multiplied using the "Dot Product" (also see Cross Product). Calculating. The Dot Product is written using a central dot: a · b This means the Dot Product of a and b. We can calculate the Dot Product of two vectors this way: a · b = |a| × |b| × cos(θ) Where: |a| is the magnitude (length) of vector a |b| is the magnitude (length ...

Description: WebApr 25, 2024 · From MathWorld --A Wolfram Web Resource. https://mathworld.wolfram.com/DotProduct.html. The dot product can be defined for two vectors X and Y by X·Y=|X||Y|costheta, (1) where theta is the angle between the vectors and |X| is the norm. It follows immediately that X·Y=0 if X is perpendicular to Y.
