This menu may be used to specify the type of operation that the user is being quizzed on.
Choices include the following:
A guess for the magnitude (radius) of the complex vector may be entered in this field, either as a number or valid arithmetic expression.
A guess for the phase of the complex vector may be entered in this field, either as a number or valid arithmetic expression.
Pressing this button will generate a new pair of quiz vectors for the user.
Checking this box will reveal the rectangular form of the input vectors, and of the user's guess.  Unchecking it will hide the rectangular form.
This checkbox will only appear if the Add option is selected under the Operation menu.  Checking it will plot the input vectors in the Resultant Plot Box in head-to-tail fashion so that it is easier to visualize the resultant sum vector.
This checkbox will only appear if the Subtract option is selected under the Operation menu.  Checking it will plot the input vectors in the Resultant Plot Box in head-to-tail fashion so that it is easier to visualize the resultant difference vector.
Checking this box will graphically plot the correct resultant vector in the Resultant Plot Box as a black arrow so that the user's guess can be compared to it.
Input vector z1 for the quiz is displayed under this red title in polar form. You may also display the rectangular form by checking the Show Rect Form box.
Input vector z2 for the quiz is displayed under this pink title in polar form. You may also display the rectangular form by checking the Show Rect Form box.
This boxed area under the Show Answer checkbox displays a legend for the colors of all the arrows representing the vectors in the quiz.
This plot displays the input complex vectors for the quiz.
This plot displays the resultant vector guessed by the user as a blue arrow.  It may be updated either by clicking on it after changing a guess value, or pressing Enter in the text field immediately after changing a guess value.  The correct resultant may also be displayed as a black arrow if the Show Answer box is checked.
This menu displays the actual magnitude, phase, and rectangular form of the resultant vector appropriate to the choice selected in the Operation menu.
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 arrow line widths.  Enter a value in the text field to specify the thickness of the arrows.  Pressing OK will close the window and apply the new arrow width to the gui; pressing Cancel will close the window, making no changes to the previous arrow width.
