Critical Background Knowledge cont…

• Relate the domain of a function to the relationships it describes (I.F.IF.5, II.F.IF.5) • Familiarity with function notation and domain (I.F.IF.2) • Understand the definition of function (8.F.1, I.F.IF.1) • Independent, dependent variables and input/output (8.F.1)

• Understand radian measure (III.F.TF.1) • Understand radian measure (III.F.TF.1) • Define trigonometric ratios (II.G.SRT.6)

• Use trigonometric ratios to solve problems (II.G.SRT.8) • Relate the domain of a function to its graph (II.F.IF.5)

• Understand that trigonometric ratios are defined by acute angles in similar triangles (II.G.SRT.6) • Use trigonometric ratios and the Pythagorean Theorem to solve right triangles (II.G.SRT.8) • Inverse trigonometric functions (III.F.TF.6) • Model periodic phenomena (III.F.TF.5) • Solve trigonometric equations • Understand that the graph of an equation in two variables is the set of all its solutions plotted on a coordinate plane (I.A.REI.10) • Explain why the x-coordinate is the solution of the system of equations where f(x) = g(x) (I.A.REI.11) • Identify when two expressions are equivalent (6.EE.4); understand that rewriting an expression in different forms

can shed light on problems and how quantities are related (7.EE.2) • Write a quadratic function in different but equivalent forms (II.F.IF.8)
