Curriculum Framework

AR.Math.Content.HSN.RN.A.1: Explain how extending the properties of integer exponents to rational exponents provides an alternative notation for radicals.

AR.Math.Content.HSN.RN.B.4: Simplify radical expressions. Perform operations (add, subtract, multiply, and divide) with radical expressions. Rationalize denominators and/or numerators.

Operations with Radical Expressions

Simplifying Radical Expressions

AR.Math.Content.HSN.CN.A.1: 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.

Points in the Complex Plane

Roots of a Quadratic

AR.Math.Content.HSN.CN.A.2: Use the relation i² = -1 and the commutative, associative, and distributive properties to add, subtract, and multiply complex numbers.

AR.Math.Content.HSN.CN.A.3: Find the conjugate of a complex number. Use conjugates to find quotients of complex numbers. Use conjugates to find moduli.

AR.Math.Content.HSN.CN.B.4: Represent complex numbers on the complex plane in rectangular and polar form (including real and imaginary numbers). Explain why the rectangular and polar forms of a given complex number represent the same number.

AR.Math.Content.HSN.CN.B.5: Represent addition, subtraction, multiplication, and conjugation of complex numbers geometrically on the complex plane; use properties of geometrical representation for computation.

AR.Math.Content.HSN.CN.C.7: Solve quadratic equations with real coefficients that have real or complex solutions.

AR.Math.Content.HSN.VM.A.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).

AR.Math.Content.HSN.VM.A.2: Find the components of a vector by subtracting the coordinates of an initial point from the coordinates of a terminal point.

AR.Math.Content.HSN.VM.A.3: Solve problems involving velocity and other quantities that can be represented by vectors.

AR.Math.Content.HSN.VM.B.4: Add and subtract vectors. 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. Given two vectors in magnitude and direction form, determine the magnitude and direction of their sum. 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. Perform vector subtraction component-wise.

AR.Math.Content.HSN.VM.B.5: Multiply a vector by a scalar. Represent scalar multiplication graphically by scaling vectors and possibly reversing their direction; Perform scalar multiplication component-wise, e.g., as 𝘤(𝘷ₓ, 𝘷 subscript 𝘺) = (𝘤𝘷ₓ, 𝘤𝘷 subscript 𝘺). Compute the magnitude of a scalar multiple cv using ||cv|| = |c|v. Compute the direction of cv knowing that when |c|v ≠ 0, the direction of cv is either along v (for c > 0) or against v (for c < 0).

AR.Math.Content.HSN.VM.C.7: Multiply matrices by scalars to produce new matrices (e.g., as when all of the payoffs in a game are doubled).
