"WebIf an angle 0 ≤ θ ≤ 180 ∘ is acute then cos will be positive. If it is obtuse then cos will be negative. If then cos 0. Given two non-zero vectors and v separated by an angle θ, we have cos θ = u ⋅ v ‖ u ‖ ‖ v ‖ Since and are both positive, the sign of cos is the sign of u ⋅ v. So the angle is acute if u ⋅ v > 0 and obtuse if u ⋅ v < 0. " - Find the cosine of ∠v
