- HSF-TF.B.5Choose trigonometric functions to model periodic phenomena with specified amplitude, frequency, and midline.*
- HSF-TF.B.6(+) Understand that restricting a trigonometric function to a domain on which it is always increasing or always decreasing allows its inverse to be constructed.
- 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.â
