Students will practice solving trigonometric equations by factoring with this quiz game. This includes multiple - choice questions with nine equations that require the use of Pythagorean, reciprocal, quotient and double angle identities. The focus is on finding both the general and specific solution of a trigonometric equation. Problems range in difficulty. At first, students solve all the problems. (After that they will need their answers to find out the configuration of a constellation). Students are also given a figure with shapes of a circle, called “stars”. Nine of them form the configuration of a constellation. These nine “stars” are labeled with the correct answers of students’ questions. Students connect the “stars” of the constellation with straight lines in a specified sequence. At last, they try to identify the constellation. Recording sheets are included for students to show work. An answer key is included as well. This activity can be used as individual practice or in a small group of three. It could also be used as an assessment .

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.

This activity practices solving basic trigonometric equations. Students must find their primary solutions in the specific interval (0 ; 2π] and give answers in radian form. The process of solving involves only the use of the reciprocal identities and algebraic manipulation (such as collecting like terms) to isolate the trigonometric function on one side of the equation. Partners will each have their own set of fourteen equations. All the equations are well thought so the solutions of each equation on the specified interval are only two. The amusing part of this activity is creating compound words corresponding to each solution set of the trigonometric equations given. Partner A’ s equations are equivalent to partner B’ s equations, so the compound words made by one partner will be the same as the words made by the other partner. Thus, partners will be satisfied to know that they both have worked correctly and will be encouraged to collaborate. Activity Directions: Partners start solving individually their own problems. Once they have found the solution set of each equation, they are given two tables to use. There is a word corresponding to each radian written in table 1 . Using this table, students find which two words correspond to each solution set of their equations and make compound words. They record the solution set of each trigonometric equation and write down the compound word corresponding to it in table 2 . Students show detailed solutions on student recording sheets specially designed for this activity or they can solve the problems on a separate sheet of notebook paper. All answer keys are included.
