I couldn't make a theta. Press the graph button and you should see a graph of the equation. You can use the calc button to find the zero which is the x value where y=0. To find the zero, press gold calc and enter 2 which is for finding zeros. Move left cursor so that it is below the x axis and press enter. Then, move cursor above x axis and press enter. Press enter again (no guess needed) and you will read x=4 and y=0.
