Presentation Transcript

  1. Graphing the Reciprocal Functions Students will graph the reciprocal trigonometric functions using transformations. Students will write equations of the reciprocal trigonometric functions.

  2. HW Review • Reciprocal of cosine • Vertical Stretch by 2 • Vertical Shift down 3 • Horizontal Stretch by 4 • Horizontal Shift left π

  3. GROUP WORK • 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.

  4. Goals: • Students will graph the reciprocal trigonometric functions using transformations. • Students will write equations of the reciprocal trigonometric functions.

  5. y= sin x y = cos x y = tan x

  6. y = cscx y = sec x y = cot x

  7. How to mark your number lines Counting by

  8. How to mark your number lines Counting by

  9. Worksheet #2Matching Equations to Graphs • Hint: Do any of the equations show a horizontal shift? • Viewing Windows should be written as follows: • X axis: • Y axis:

  10. Conclusion • HW: • Be sure that you have 4 problems from the graphing worksheet completed and checked. • Tuesday: Review • Continue work in groups to complete the matching exercise and writing equations from graphs. • Quiz: Wednesday 2/26
