Cross Product Calculator: solve cross product problems step-by-step. Clear formula, worked example, and FAQs included.
2×2 determinant: det(A) = ad − bc for [[a,b],[c,d]]
2×2 inverse: A⁻¹ = (1/det(A)) × [[d,−b],[−c,a]]
Dot product: a·b = Σ(aᵢ × bᵢ) (scalar result)
Cross product: a×b = [a₂b₃−a₃b₂, a₃b₁−a₁b₃, a₁b₂−a₂b₁] (3D vector result)
