HSN.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.A1
Know there is a complex number i such that i² = -1, and every complex number has the form a + bi with a and b real.
October 1, 2018HSN.CN.A2
Use the relation i² = -1 and the commutative, associative, and distributive properties to add, subtract, and multiply complex numbers.
