Last week, we developed our understanding of the sine and cosine functions by connecting their graphical, numerical, and geometric representations. This week we explore those functions and the trig function that composes them. We'll assemble a network-of-sorts using the graphing calculators and use that network to structure the mathematical activity using students' contributions. We move back and forth between big ideas and their instances. And we use big words like periodic, amplitude, midline, symmetry, transformation, phase shift, inverse, domain and range, global max and min, roots/zeros, and arc length.
This link takes you to a collection of trig-related applets, some of which we'll use in class to explore these functions.
Wolfram|Alpha is also a handy tool for exploring functions and other mathematical objects.
Students who haven't completed the activity from week 5 should do so before heading on to this exploration.
