Differential Equation Graph Window Operations
(1) Perform the operation under “Inputting an Nth-order Differential Equation and Initial
Conditions, and then Graphing the Solutions” on page 14-4-1.
• Performing all of the steps will produce a graph like the one shown below to appear
on the Differential Equation Graph window.
(2) Tap [Analysis] - [Select] or the toolbar ' button.
(3) Tap one of the initial condition dots to select it.
• Here we will tap the bottom dot, which is the Initial Condition 1 setting (xi, y1i, y2i) =
(0, −1, 0).
These dots are the currently configured
initial conditions.
The dot you tap becomes a white circle (5),
which indicates that it is selected.
(4) Use the stylus to drag the dot to another location.
• The applicable initial location will change to the coordinates of the location where you
release the stylus after dragging the dot. After modifying an initial condition, the
solution will be redrawn accordingly.
