Common Core Math - HS Functions
Lesson Plan
Solve trigonometric equations
Goals / Objectives
Isolate the trigonometric expression in an equation arising from a modeling context
Apply arcsin, arccos, or arctan to find a principal solution to a trigonometric equation
Use periodicity and symmetry to find all solutions within a specified interval
Use technology (calculator) to evaluate inverse trig functions for non-standard values
Interpret solutions in terms of the real-world context (e.g., "the height reaches 40 feet at t = 2.3 minutes")
Determine which solutions are meaningful in the modeling context and discard extraneous ones
Standards
HSF.TF.B.7
HSF.TF.B.7: (+) Use inverse functions to solve trigonometric equations that arise in modeling contexts; evaluate the solutions using technology, and interpret them in terms of the context.
