Law of cosines parallelogram calculator
Web6 apr. 2024 · In triangle ACB, we have from triangle law of vector addition AB+BC=AC. Substituting the value of AB and BC, we get a+v=w Hence, we have u+v=w, which is the parallelogram law of vector addition. The angle between vectors a and v is π − B So let θ = π − B ⇒ B = π − θ Now by cosine rule in triangle ACB, we have WebSolution: Using the parallelogram law of vector addition formulas, we have R = √ (P 2 + Q 2 + 2PQ cos θ), β = tan -1 [ (Q sin θ)/ (P + Q cos θ)] For this, first, we need the magnitudes of vectors P and Q. P = √ (1 2 + 2 2) = √5, Q = √ (2 2 + 4 2) = 2√5 R = √ (√5 2 + (2√5) 2 + 2PQ cos θ) = √ (5 + 20 + 2×√5×2√5 cos 60°) = √ (25 + 20/2)
