Differential Equation Graph Window Operations

(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.
