Students study the concept of tangent of a unit circle. In this unit circle lesson, students explore the mathematical history of the trigonometric ration, tangent, through an interactive date-gathering construction that simulates an experience that mirrors how values of trig functions may have been approximated.
Students use Geometer's Sketchpad software to explore angles and theorems of circles. They examine the relationship between angle measure and arc measure, and they create and measure central angles, inscribed angles, tangents, chords and secants. Students complete an activity sheet which leads them to investigate secants and tangents. Additional multi-sensory activities are listed.
Students explore the concept of the unit circle. In this unit circle instructional activity, students create a scatter plot of the sine, cosine, and tangent function using data from the x and y values on the unit circle. Students generalize the tangent, sine, and cosine relationships.
A plethora of lessons from Key Curriculum press to explore real-world applications using vectors, time, distance, and trig functions. There are a wide variety of examples, diagrams, and activities to learn trigonometric ratios, unit circle, transforming functions, direct proof, two-column proof, and conditional proof. There are many lessons and it would take several days to cover all the topics.
