Trigonometric Graphs

Students will use jigsawing in order to learn about the graphs of the trigonometric functions.

Indiana Standards

PC 4.5 Define and graph trigonometric functions.

PC 4.6 Find domain, range, intercepts periods, amplitudes, and asymptotes of trigonometric functions.

1. Students will be able to use the graphs of the trigonometric functions.
2. Students will be able to find the amplitude and period of the trig functions.

Day 1:

1. Warm-up:  Where do you see patterns in everyday life? (ie the seasons)
2. Students will get into groups for each of the trig functions.  They will need to find the Basic graph, Period, Amplitude, Intercepts, Domain , Range, Phase shift, Vertical shift.  They will need to make a study sheet so they can teach other students.
3. Exit question: Name something you learned.  Name something you need clarification on.

Day 2:

1. Warm-up: find the value of pi/2, pi, and 3p8i/2 for the function you studied yesterday.
2. Teacher will answer any questions from the exit question yesterday.
3. Students will get into 2 (or 3) groups, in order to explain their graph to the other students. (each student will take notes).
4. Exit Question: Compare and contrast your graph and either the reciprocal or inverse function.

• Pencil/Pen (students)
• Paper/notebook (students)
• Book
• Trig graph paper

Check student's work for completeness and accuracy.  Then assign problems so they may practice graphing each of the functions.
