Trigonometric Functions
(already made -- ready to use file)

(Materials for use with Geometer's Sketchpad 4.0 or higher -- not GSP 3.0)

Investigate sine, cosine, tangent, cosecant, secant, cotangent, sine inverse, cosine inverse, and tangent inverse functions.  Worksheets involve questions about sinusoidal functions with vertical shifts and phase shifts.  The pages with all options "in view" are shown below.

  This program was designed to be shown on a 1024 x 768 computer screen.
(This is one file containing 10 different pages.)

Each of the 9 trig investigations allows for the dragging of an x-coordinate to compare y-values on each graph and the viewing (or hiding) of various companion functions.

The pages have been set to open with only one function in view.  Other functions appear with a mouse click.  Do NOT "save" changes when done and these original settings will remain for the next class or viewing.

This package is great for classroom demonstration as items are large enough to be seen in a classroom setting.  If used in conjunction with the accompanying worksheets, the package is ideal for student exploration.

This package is designed for the Algebra2 level student, but could be used for a more advanced review of trigonometric graphs as well.

These .gsp and .pdf files are to be used only by individual teachers in their own classrooms.
Please refer to Terms of Use.

General (and simple) Directions:  
  • Be sure that the students have chosen the arrow in the upper left hand corner of the screen.
  • Be sure that the screen is maximized so that the tabs at the bottom of the screen are visible.  (The middle box at the right is showing a screen in maximized view.)
  • Read and follow the directions that appear on the page. 
    "SHOW" means the values will appear when you click on the button.  "HIDE" means the values will disappear when you click on the button. 
  • To end the exploration, choose FILE - CLOSE.  When the box asking if you wish to "Save Changes" appears, choose NO.  This will keep the file in the same state as when you started working.  None of the students' changes (or messing) will be saved.
