OH.Math.HSN.VM: Vector and Matrix Quantities

OH.Math.HSN.VM.A: Represent and model with vector quantities.

OH.Math.HSN.VM.1: Recognize vector quantities as having both magnitude and direction. Represent vector quantities by directed line segments, and use appropriate symbols for vectors and their magnitudes, e.g., v, | v |, ||v||, v.

OH.Math.HSN.VM.B: Perform operations on vectors.

OH.Math.HSN.VM.4: Add and subtract vectors.

OH.Math.HSN.VM.4a: Add vectors end-to-end, component-wise, and by the parallelogram rule. Understand that the magnitude of a sum of two vectors is typically not the sum of the magnitudes.

OH.Math.HSN.VM.4b: Given two vectors in magnitude and direction form, determine the magnitude and direction of their sum.

Vectors

OH.Math.HSN.VM.4c: Understand vector subtraction v - w as v + (-w), where -w is the additive inverse of w, with the same magnitude as w and pointing in the opposite direction. Represent vector subtraction graphically by connecting the tips in the appropriate order, and perform vector subtraction component-wise.
