High School: Number and Quantity
HSN.VM.A1
(+) 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).

(+) Find the components of a vector by subtracting the coordinates of an initial point from the coordinates of a terminal point.
October 1, 2018HSN.VM.A3
(+) Solve problems involving velocity and other quantities that can be represented by vectors.
October 1, 2018HSN.CN.A3
(+) Find the conjugate of a complex number; use conjugates to find moduli and quotients of complex numbers.
October 1, 2018HSN.CN.B4
(+) Represent complex numbers on the complex plane in rectangular and polar form (including real and imaginary numbers), and explain why the rectangular and polar forms of a given complex number represent the same number.

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.
October 1, 2018HSN.CN.B5
(+) Represent addition, subtraction, multiplication, and conjugation of complex numbers geometrically on the complex plane; use properties of this representation for computation. For example, (-1 + √3 i)3 = 8 because (-1 + √3 i) has modulus 2 and argument 120°.

Given two vectors in magnitude and direction form, determine the magnitude and direction of their sum.
October 1, 2018HSN.CN.B6
(+) Calculate the distance between numbers in the complex plane as the modulus of the difference, and the midpoint of a segment as the average of the numbers at its endpoints.
October 1, 2018HSN.VM.B4c
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.
