In this video I go further into the dot product and this time show that two vectors are perpendicular if their dot product is equal to zero. Since a ⋅ b = |a| |b| cos θ, then when the angle θ = π/2 radians or 90 degrees, then cosine π/2 = 0 and thus the dot product is equal to 0. This is a great way to verify if any 2 vectors are perpendicular, as which I also illustrate with an example.
