WebThe dot product is used in Physics to define the work of a force. In the animation below b’ represents b rotated 90 0. Since the cosine is the sine complement, the area of the parallelogram that vectors a and b’ span is the absolute value of the dot product a · b. You can move both vectors a and b to see their dot product.
