This is a way to use the TI-Navigator™ to check for an understanding of sin, cos, and tan before you move onto word problems.
Before the Activity
You will need to teach the three trig ratios (sin, cos and tan).
During the Activity
Use the quick poll feature and the attached file to review the trig ratios.
After the Activity
Use the attached LearningCheck&trade to see if the students' understand trig ratios.
