Differential Equation Graph Window Operations

S To graph the solution curves by dropping an Nth-order differential

equation and matrix into the Differential Equation Graph window

Example: To drag the Nth-order differential equation y + y = exp(x) and then the initial

condition matrix [[0, 1, 0][0, 2, 0]] from the eActivity application window to the

Differential Equation Graph window, and graph the applicable solution curves

(1) On the application menu, tap

.

• This starts up the eActivity application.

(2) On the eActivity application window, input the following expression and matrix.

y + y = exp(x)

[[0,1,0][0,2,0]]

(3) From the eActivity application menu, tap [Insert], [Strip], and then [DiffEqGraph].

• This inserts a Differential Equation Graph data strip,
and displays the Differential Equation Graph window
in the lower half of the screen.

(4) Drag the stylus across “y + y = exp(x)” on the eActivity application window to select it.
