WebThe angle between two intersecting planes is defined to be the angle between their normal vectors. Find the angle between the planes x – 2 y + z = 0 and 2 x + 3 y – 2 z = 0. Find the parametric equations of the line of intersection of the two planes above. Web4 jan. 2024 · Find the dot product of the vectors. Divide the dot product by the magnitude of the first vector. Divide the resultant by the magnitude of the second vector. Mathematically, angle α between two vectors can be written as: α = arccos [ (xa · xb + ya · yb + za · zb) / (√ (xa² + ya² + za²) · √ (xb² + yb² + zb²))]
