Differential Equation Graph Window Operations

STo 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.
