G1:A graph of FN(x) is plotted here when the Plot Graph button is clicked. The function of x which is plotted is determined by the setting of the Sin, Cos and Both buttons. Whilst over the graph window the pointer changes to a cross hair.
G2:Click here to plot a graph of FN(x). The graph plotted is determined by the setting of the Sin, Cos and Both buttons.
G3:Click here to reset the graph window and display just the axies.
G4:Click here to select either Degree or Radian graduations on the graph scale.
G5:Click here to select the FN(x) which is plotted when the Plot Graph button is clicked. The graph of Sine(x) is plotted in red, Cosine(x) in blue.
G6:The values of x, Sine(x) and Cosine(x) are displayed here as the pointer is moved across the graph window.
