Vectors and Geometry—vector magnitude, unit vector calculation, position vectors (OA, OB, AB), geometric interpretation Coordinate Geometry—distance between points, midpoint, vector directions in coordinate plane Algebra—solving equations involving parameters (e.g. solving for p when vector magnitudes are related), simplification Trigonometry and Direction—vector directionality, scalar multiples, understanding vector diagrams Mathematical Reasoning—multi-step problem-solving, logical deduction based on vector constraints
