GrAssign - Solving Trig Equations using Desmos

  Instructions

          1.   On the answer sheet, algebraically solve for x. 

        2.   Determine the exact solutions - record as radians, no decimals.

                     (This must be completed before you use Desmos)

        3.   Using Desmos, graph the two expressions. (Reread the two notes in the above example.)

                      If there are two equations, both must be included in Desmos, which might result in 4 equations that need to be graphed.

        4.   Record the graphical solutions as a Desmos point, then click on the label box to make sure these solutions are visible.

                       i.e. x = (pi/3, 1/2) [see the above image]

        5.   Write a statement comparing your algebraic solution to the graph's points of intersection.  Are your solutions correct?

                      If not, explain why not.

        6.   Take a screenshot of your equations, points, and the graph. (Include your name). 

                    [See the graph image in the above example.]

        7.  After doing the 3 equations, explain what you learned using this method of finding solutions.

        8.   Using your TI grapher, graph problem #3 to determine if using a grapher would also help you find a trig equation's solution(s). 

                    Briefly describe the results and your thoughts.

         9.  Save each problem as follows:

                        1_TrigEqDes_LastName

                   2_TrigEqDes_LastName 

                   3_TrigEqDes_LastName

        10.  Upload to Google Classroom
