Tangent Investigation • Remember: • Fill out a table for the five key points using the formula for tangent and the unit circle • Then answer the reflection question
Observations? • What happens to the graph of tangent at and ? discontinuities in the graph • The graph of tangent has vertical asymptotes at those two points.
Think-Pair-Share • What do you think is the period of f(t) = tan(t)? π • What do you think is the amplitude of f(t) = tan(t)? Why? DNE because of the vertical asymptotes • What do you think is the range of f(t) = tan(t)? (–∞, ∞)
Think-Pair-Share, cont. • What do you think is the domain of f(t) = tan(t)? where n is any integer (the domain excludes and any multiples of )
Transformations of Tangent • Because tangent graphs don’t have an amplitude, they follow the format f(t) = tan(bt – c) + d
Your Turn: • Complete problems 1 – 3 in guided notes. 1. 2. 3.
