F1 – Prev Soln (Previous Solution)
F2 – Next Soln (Next Solution) The Prev Soln and Next Soln options will cycle backward and forward,
respectively, through the available solution sets for math solvers that may have multiple solutions. A
status line near the bottom left of the screen appears once a valid solution has been found. The solution
status line indicates the total number of solutions and the solution number that is currently represented by
the graphic display on the right. For example, in an Arc Tangent Arcs math help, the display solution
status may be “- Solution 1 of 8 -“. In this case, the Prev Soln and Next Soln can be used to cycle through
all eight of the solutions.
F3 – Clear All The Clear All option removes all solutions. It sets all fields for a particular solver to UNKNOWN.
F4 – Prev Solver
F5 – Next Solver The Prev Solver and Next Solver options cycle backward and forward, respectively, through the
various math help solvers. These options are shortcuts which have the same effect as pressing ESC to
reach the main math help menu, navigating to the previous or next math help option, and then pressing
ENTER.
F6 – Hide Math The F6 - Hide Math option exits math help mode and returns to the operation edit menu. Pressing
F6 - Math Help to invoke Math Help again will restore Math Help exactly as you left it. After copying
values from Math Help, you can press F6 - Hide Math to hide Math Help, and then hit F10 - Accept to
accept the values entered.
F7 – Copy <<<
F8 – Copy >>> The F8 - Copy <<< option will move the value from the selected edit operation field into the
selected math help menu field and the Copy >>> operation will move the value from the selected math
help menu field into the selected edit operation field. For both options, the selected fields in the math help
menu and the operation edit menu are advanced. Only when the graphics display is off will the Copy
operations actually copy values and advance field selections.
The currently selected fields have either a box drawn around them or are highlighted depending upon which menu is
active. The active menu, which is either the math operation menu on the left hand side or the operation edit menu on
the right hand side, depicts the selected field by highlighting the entire field. The non-active menu displays the active
field with a box drawn around it. Use the arrow keys to select fields as described below.
F9 – Graphic On/Off The F9 - Graphic On/Off option will toggle the graphical representation of the math help
menu on the display.
(Arrow Keys) – Select Fields
The LEFT and RIGHT arrow keys are used to navigate between the math menu and the edit menu. The UP and
DOWN arrow keys are used to navigate within a menu. To choose fields for the “Copy” option, above, use the UP
and DOWN arrow keys to highlight the desired field in the menu and use the LEFT or RIGHT arrow keys to switch
menus.
Other features common to all Math Help operations
In some math help operations, there will be an asterisk ‘*’ character that appears immediately to the right of a field.
This character marks the field as a “given” field, which means that the value of this field will be held constant in the
process of solving the math equations.
