| 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. |  |  |
