WebApr 7, 2024 · Your final equation for the angle is arccos (. ). For a quick plug and solve, use this formula for any pair of two-dimensional vectors: cosθ = (u 1 • v 1 + u 2 • v 2) / (√ (u 12 • u 22) • √ (v 12 • v 22 )). The cosine formula tells you whether the angle between vectors is acute or obtuse.
