(5) Drag the selected expression to the Differential Equation Graph window.

• This registers y + y = exp(x) on the differential equation editor ([DiffEq] tab). The
Differential Equation Graph window contents do not change at this time.

(6) Drag the stylus across “[[0,1,0][0,2,0]]” on the eActivity application window to select it.

(7) Drag the selected matrix to the Differential Equation Graph window.

• This graphs the solution curves of y + y = exp(x) in accordance with the initial
condition defined by the matrix, and registers the initial condition in the initial
condition editor ([IC] tab).

Tip

An Nth-order differential equation of the form f (y’, y’’…,x) dropped into the Differential

Equation Graph Window will be treated as f (y’, y’’…,x) = 0.
