The completed table is: | | | | | | | | | | | | | | | |---|---|---|---|---|---|---|---|---|---|---|---|---|---| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
Step 2: Draw the graph of and . a) Set up the axes on the provided grid. The x-axis should represent angles from to . A suitable scale would be for . b) The y-axis should represent values from approximately to . A suitable scale would be for unit. c) Plot the points from the completed table for and draw a smooth curve through them. Label this curve . d) Plot the points from the completed table for and draw a smooth curve through them. Label this curve .
Step 3: Use the graph to find the values of when . The equation can be rewritten as . This means we need to find the x-coordinates of the intersection points of the two graphs, and . From the graph, locate the points where the two curves intersect. The intersection points occur at approximately: and
Step 4: Use the graph to find the values of when . This asks for the y-coordinates of the intersection points found in Step 3. At , read the corresponding y-value from either graph. At , read the corresponding y-value from either graph. The values of are approximately and .
