Vectors in ℝⁿ

About this app

Vectors beyond arrows: monthly sales as a vector in ℝ¹², position + velocity as a state in ℝ⁶. a + b, r·a and a·b component-wise, the dot product as a running sum, magnitude and cos φ as the similarity of two curves (b = 2·a ⇒ cos φ = 1), time step position + Δt·v in 3D.
