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.
