Big Idea:

### Trigonometric functions are characterized by the period and amplitude.

1 week

Evidence of Understanding

• interpret the features of a trig function from its graph, table, or equation
• graph f(x) = sinx and g(x) = cosx and describe the relationship between inputs and outputs
• given any input, use the graph to identify the output
• identify the period, amplitude, midline, and frequency for any trig function
• explain connections between the unit circle and sine, cosine, and tangent functions
• describe restrictions on the domain and range
• identify intervals that are increasing, decreasing, positive, and negative
• represent trigonometric functions in multiple formats, including graphically, in table form, and as a function rule

• describe trig functions in relation to its parent function, f(x) = sinx, cosx, or tanx
• given the parent graph and another trig graph, describe how a transformation on the parent function impacts the function’s amplitude, midline, period and/or frequency
• create a graph, table of values, or equation for a function from a stated transformation
• write the function rule from the graph
• possible extension: explore parent functions of f(x) = cscx, secx, or cotx and create a graph, table of values, or equation for a function from a stated transformation

• use trigonometric functions to model different contexts
• solve a real-world situation by creating and using a trigonometric function rule, graph, or table
• analyze values to justify a trigonometric function model (and not linear, quadratic, or exponential)
• interpret solutions using trigonometric function models
• accept and reject possible solutions based on the context of the situation and the limitations on  reasonable domain and range values
