Students will graph the reciprocal trigonometric functions using transformations. Students will write equations of the reciprocal trigonometric functions.

 Reciprocal of cosine  Vertical Stretch by 2  Vertical Shift down 3  Horizontal Stretch by 4  Horizontal Shift left π

 Move to your assigned groups. (A, B, or C)  The assigned group leader will review the instructions for your group assignment.  Work cooperatively. Check to be sure that everyone in the group understands and completes the assignment.  Only ask for help if everyone in the group has been consulted and you ALL have the same question.
