This activity practices solving trigonometric equations of quadratic type. It includes multiple - choice with twelve equations and a brief story about the history of trigonometry to be completed. The equations require the use of Pythagorean, reciprocal, quotient, double angle identities and the quadratic formula. Problems range in difficulty.
Activity Directions: Students must solve all the problems and find specific solutions. The answers they get will give them pieces of a brief story about history of trigonometry. Studying the history of trigonometry will throw light on the nature of the discipline. It will help students gain a deeper understanding of the trigonometry they have already studied by seeing how it was developed over time.
Recording sheets are provided for students to show all work.
An answer key is included.
This activity can be used as individual practice, as a partner activity (each partner will get a sheet that has only six equations to solve) or in small groups of 3. It could also be used as an assessment.
