A guess for the amplitude of the sinusoid may be entered in this field, either as a number or valid arithmetic expression.
A guess for the cyclic frequency of the sinusoid may be entered in this field, either as a number or valid arithmetic expression.
A guess for the phase of the sinusoid may be entered in this field, either as a number or valid arithmetic expression.
Checking this box will superimpose a plot of the guessed sinusoid onto that of the quiz sinusoid in the Plot Box in addition to displaying its mathematical formula immediately above the box.  Unchecking it will remove the guessed plot and formula.
Pressing this button will generate a new quiz sinusoid.
This box displays the plot of the quiz sinusoid whose characteristics are to be guessed.   If the Show Guess box is checked, a plot of the guessed sinusoid entered by the user is displayed on top of the quiz sinusoid.
This menu displays the actual amplitude, frequency and phase of the quiz sinusoid.
This menu item will reveal two options:  Novice or Pro.  Whichever option is checked will determine the difficulty level of the quizzes produced by pressing the New Quiz button.
This menu item enables adjustment of the plotting line widths.  Use the sliding bar to change the current line width; the preview box above the sliding bar will update to show the currently selected width.  Pressing OK will close the window and apply the new line width to the gui.
